The function `flymake-ler-make-ler' can't possibly work as an backward
compatible interface to existing extensinos (even purely hypothetical
ones, since none are known). This is because every diagnostic
considered by Flymake has to passed to a report-fn function.

have a construct like the above. Pass this as argument to
c-font-lock-declarators.

being processed starts before the function's starting position.

The 'shr-external-rendering-functions' variable was previously only
honored in the shr-descend function, now all direct calls to the
shr-tag-* functions have been replaced by a call to
'shr-indirect-call' which tries using an alternative rendering
function first.

Although the Lisp manual said that ‘format’ returns a
newly-allocated string, this was not true for a few cases like
(format "%s" ""), and fixing the documentation to allow reuse of
arguments lets us improve performance in common cases like
(format "foo") and (format "%s" "foo") (Bug#28625).
* doc/lispref/strings.texi (Formatting Strings):
* etc/NEWS:
Say that the result of ‘format’ might not be newly allocated.

* src/dbusbind.c (XD_OBJECT_TO_STRING):
* src/editfns.c (Fmessage, Fmessage_box):
* src/xdisp.c (vadd_to_log, Ftrace_to_stderr):
Just use Fformat or Fformat_message, as that’s simpler and no
longer makes unnecessary copies.
* src/editfns.c (styled_format): Remove last argument, as it
is no longer needed: all callers now want it to behave as if it
were true. All remaining callers changed. Make this function
static again. Simplify the function now that we no longer
need to worry about whether the optimization is allowed.
Also correct two bugs where deleting WS at a BOL could leave an untyped
function declaration unfontified.
* lisp/progmodes/cc-engine.el (c-find-decl-spots): Don't set the flag
"top-level" when we're in a macro.

Mode as a implicitly typed function declaration.
(c-just-after-func-arglist-p): Don't get confused by "defined (foo)" inside a

(getcjmp): Define to current thread's 'm_getcjmp'.
* src/thread.c (maybe_reacquire_global_lock): Switch to main
thread, since this is called from a SIGINT handler, which always
runs in the context of the main thread.
* src/lisp.h (sys_jmp_buf, sys_setjmp, sys_longjmp): Move the
definitions before thread.h is included, as thread.h now uses
sys_jmp_buf.
* src/keyboard.c (getcjmp): Remove declaration.
(read_char): Don't call maybe_reacquire_global_lock here.
(handle_interrupt): Call maybe_reacquire_global_lock here, if
invoked from the SIGINT handler, to make sure
quit_throw_to_read_char runs with main thread's Lisp bindings and
uses the main thread's jmp_buf buffer. (Bug#28630)
Problem reported by N. Jackson (Bug#28597).
This improves an earlier suggestion by Robert Pluim (Bug#28597#47).

Rewrote a significant part of the Flymake backend API. Flymake now
ignores the return value of backend functions: a function can either
returns or errors. If it doesn't error, a backend is no longer
constrained to call REPORT-FN exactly once. It may do so any number
of times, cumulatively reporting diagnostics. Flymake keeps track of
outdated REPORT-FN instances and disconsiders obsolete reports.
Backends should avoid reporting obsolete data by cancelling any
ongoing processing at every renewed call to the backend function.
Consolidated flymake.el internal data structures to require less
buffer-local variables. Adjusted Flymake's mode-line indicator to the
new semantics.
Adapted and simplified the implementation of elisp and legacy
backends, fixing potential race conditions when calling backends in
rapid succession.
Added a new test for a backend that calls REPORT-FN multiple
times. Simplify test infrastructure.

Maybe squash in that one where I remove many obsoletes
Too early to decide what will be in it, if anything. Though "M-n" and
"M-p" would be great.
* lisp/progmodes/flymake-ui.el (flymake-mode-map): New variable
Also fix behaviour whereby flymake wouldn't react to a change in the
variable.

(flymake-warning-bitmap): Update bitmaps.
(flymake-note-bitmap): New defcustom.
(flymake-double-exclamation-mark): New bitmap.
(flymake-error, flymake-warning, flymake-note)
(flymake--highlight-line): 'bitmap property must be a symbol.
Also set default face to flymake-error.
(flymake--fringe-overlay-spec): Bitmap property can be a
variable symbol.
The first of these problems is longstanding: if an error-less B.h is
included from error-ridden A.h, flymake's legacy parser will panic
(and disable itself) since it sees a non-zero exit for a clean file.
To fix this, recommend returning 'true' in the documentation for the
check-syntax target.
Another problem was introduced by the parser rewrite. For error
patterns spanning more than one line, point may be left in the middle
of a line and thus render other patterns useless. Those patterns were
written for the old line-by-line parser. To make them useful again,
move to the beginning of line in those situations.
The third problem was also longstanding and happened on newer GCC's:
The "In file included from" prefix confused
flymake-proc-get-real-file-name. Fix this.
Also updated flymake--diag-region to fallback to highlighting a full
line less often.
Add automatic tests to check this.
* lisp/progmodes/flymake-proc.el
(flymake-proc--diagnostics-for-pattern): Fix bug when patterns
accidentally spans more than one line. Don't create
diagnostics without error messages.

* doc/misc/flymake.texi (Example---Configuring a tool called

Loading flymake-elisp.el doesn't setup flymake-mode to turn on
automatically, but it affects emacs-lisp-mode-hook so that
flymake-diagnostic-functions is setup with a suitable buffer-local
value. The variable flymake-diagnostic-funtions in every live
emacs-lisp-mode buffer is also adjusted.
* lisp/progmodes/flymake.el (top): Require flymake-elisp.

Add filters, useful for backends like the upcoming
flymake-elisp-checkdoc backend, for example, which litters everything
with low-priority notes.
Also re-implement wraparound for flymake-goto-next-error. Manual
mentions this, so it's probably a good idea to keep it. Added a new
customization variable flymake-wrap-around to control it.
* lisp/progmodes/flymake.el (flymake-goto-prev-error)
(flymake-goto-next-error): Accept FILTER argument.

Lay groundwork for multiple active backends in the same buffer.
Backends are lisp functions called when flymake-mode sees fit. They
are responsible for examining the current buffer and telling
flymake.el, via return value, if they can syntax check it.
Backends should return quickly and inexpensively, but they are also
passed a REPORT-FN argument which they may or may not call
asynchronously after performing more expensive work.
REPORT-FN's calling convention stipulates that a backend calls it with
a list of diagnostics as argument, or, alternatively, with a symbol
denoting an exceptional situation, usually some panic resulting from a
misconfigured backend. In keeping with legacy behaviour,
flymake.el's response to a panic is to disable the issuing backend.
The flymake--diag object representing a diagnostic now also keeps
information about its source backend. Among other uses, this allows
flymake to selectively cleanup overlays based on which backend is
updating its diagnostics.

flymake--running-backends and flymake--disabled-backends.
(flymake-find-file-hook): Simplify.
* test/lisp/progmodes/flymake-tests.el
(flymake-tests--call-with-fixture): Use flymake-is-running the
function. Check if flymake-mode already active before activating it.
Add a thorough test for flymake multiple backends
* lisp/progmodes/flymake.el (flymake--start-syntax-check):
Don't use condition-case-unless-debug, use condition-case
* test/lisp/progmodes/flymake-tests.el
(flymake-tests--assert-set): New helper macro.
(dummy-backends): New test.
Diagnostics are reported for buffers, not necessarily files. It’s the
backend’s responsibility to compute the buffer where the diagnostic is
applicable. For now, this has to match the buffer where flymake-mode
is active and which is at the origin of the backend call.
flymake.el knows nothing about line/column diagnostics (except for
backward-compatible flymake-ler-make-ler, which must yet be tested).
It’s also the backend’s reponsibility to compute a BEG and END
positions for the diagnostic in the relevant buffer.
* lisp/progmodes/flymake-proc.el
(flymake-proc--diagnostics-for-pattern): Convert LINE/COL to
region here. Check file buffer here.
(flymake-proc--process-sentinel): Don’t kill output buffer if
high enough log level.
* lisp/progmodes/flymake.el (flymake-diag-region): Make this a utility
function. (flymake--highlight-line): Diagnostic has region now.
(flymake-popup-current-error-menu): Don’t add file and line numbers to
already this silly menu. (flymake--fix-line-numbers): Remove.
(flymake-report): No need to fix diagnostics here.
