Perform 'regexp-opt' on nested 'or' forms, and after expansion of
user-defined and 'eval' forms. Characters are now turned into strings
for wider 'regexp-opt' scope. This preserves the longest-match
semantics for string in 'or' forms over composition.
* doc/lispref/searching.texi (Rx Constructs): Document.
* lisp/emacs-lisp/rx.el (rx--normalise-or-arg)
(rx--all-string-or-args): New.
(rx--translate-or): Normalise arguments first, and check for strings
in subforms.
(rx--expand-eval): Extracted from rx--translate-eval.
(rx--translate-eval): Call rx--expand-eval.
* test/lisp/emacs-lisp/rx-tests.el (rx-or, rx-def-in-or): Add tests.
* etc/NEWS: Announce.
When run with -p or -P, OMake regurgitates error messages that
prevented further progress, indented by 6 spaces. Use that fact
to ameliorate the modification done to other error message regexps.
* lisp/progmodes/compile.el (compilation-parse-errors):
When 'omake' is enabled, allow error messages to be indented by 0 or 6
spaces instead of any number of spaces, to avoid pathological
behaviour.
(compilation-error-regexp-alist-alist): Anchor the 'omake' pattern to
bol for performance. Repair the 'ruby-Test::Unit' pattern, which
relied on the previously over-generous 'omake' hack.
* etc/compilation.txt (OMake): Add examples.
* test/lisp/progmodes/compile-tests.el (compile-tests--test-regexps-data)
(compile-test-error-regexps): Add test for OMake (indented error).
Anchor the regexp at line-start to prevent quadratic behaviour when
it doesn't match (bug#39595). It's unclear whether the type tag, like
[ERROR], is always present; we keep it optional just in case.
* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
Rewrite 'maven' regexp, using rx for clarity.
* etc/compilation.txt (maven): More examples.
* test/lisp/progmodes/compile-tests.el
(compile-tests--test-regexps-data): No leading spaces; they seems to
stem from a misunderstanding in bug#11517.
This argument was added for the 'or' clause in rx, but it turned out
to be a bad idea (bug#37659), and there seems to be little other use
for it.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt): Remove KEEP-ORDER.
* doc/lispref/searching.texi (Regexp Functions):
* etc/NEWS: Remove it from the documentation.
* test/lisp/emacs-lisp/regexp-opt-tests.el (regexp-opt-test--match-all)
(regexp-opt-test--check-perm, regexp-opt-test--explain-perm)
(regexp-opt-keep-order, regexp-opt-longest-match): Simplify test.
* lisp/minibuffer.el (minibuffer--message-overlay-pos): New
function.
(set-minibuffer-message): Use it to determine where to show the
overlay with the temporary message.
* lisp/ido.el (ido-exhibit): Revert "Render Ido suggestions using
an overlay"; this restores the original code which inserted the
match-status information into the minibuffer, instead of
displaying it in an overlay with an after-string. Put the special
'minibuffer-message' text property at the beginning of the
inserted text. (Bug#39379)
* etc/NEWS:
* doc/lispref/display.texi (Displaying Messages):
* doc/lispref/text.texi (Special Properties): Document the
'minibuffer-message' text property and its effect.
* lisp/mh-e/mh-e.el, doc/misc/mh-e.texi (mh-show-mode-hook): Now that
the fix for MH-E bug #470 calls mh-show-mode-hook earlier, update the
documentation to no longer say that the message contents are available.
Thanks to 57e2ca5c50 and related changes, opening brackets at the
leftmost column inside doc strings are no longer mistaken for the
start of a defun.
* doc/lispref/tips.texi (Documentation Tips): Clarify recommendation
and move it down the list.
* etc/NEWS: Announce.
* lisp/simple.el (shell-command-dont-erase-buffer):
The default, nil, is backward compatible, i.e. it erases the buffer
only if the output buffer is not the current one; the new value 'erase
always erases the output buffer.
Update docstring.
(shell-command-save-pos-or-erase):
Add optional arg output-to-current-buffer.
Rename it so that it's not internal. All callers updated.
(shell-command-set-point-after-cmd): Rename it so that it's not internal.
All callers updated.
Adjust it to cover a side case.
(shell-command): Adjust logic to match the specification (Bug#39067).
Enable the feature when the output buffer is the current one.
(shell-command-on-region): Little tweak to follow
`shell-command-dont-erase-buffer' specification.
* test/lisp/simple-tests.el (with-shell-command-dont-erase-buffer):
Add helper macro.
(simple-tests-shell-command-39067)
(simple-tests-shell-command-dont-erase-buffer): Add tests.
* doc/emacs/misc.texi (Single Shell): Update manual.
* etc/NEWS (Single shell commands): Announce the change.
* etc/NEWS: New entry.
* lisp/progmodes/etags.el (tags-case-fold-search):
Mark as safe-local.
(find-tag--completion-ignore-case):
Extract from tags-completion-at-point-function, find-tag-tag and
etags--xref-find-definitions.
(xref-backend-identifier-completion-ignore-case):
New method. Use it here as well.
* lisp/progmodes/xref.el
(xref-backend-identifier-completion-ignore-case): New generic.
(xref--read-identifier): Use it here.
* doc/emacs/custom.texi (Find Init): Update description of how Emacs
finds its init file directory and the interaction with
$XDG_CONFIG_HOME
(Early Init File): Correct XDG location of early-init.el
* etc/NEWS: Update description to make it clear the ~/.emacs.d is
preferred, even if the XDG location exists.
* lisp/startup.el: Prefer ~/.emacs.d even if the XDG location exists.
* lib-src/emacsclient.c (open_config): Prefer home directory the XDG
location.
* lisp/progmodes/elisp-mode.el (lisp-interaction-mode):
Set lexical-binding.
* lisp/startup.el (command-line, startup--get-buffer-create-scratch):
Don't set lexical-binding here.
* doc/lispref/variables.texi:
* etc/NEWS:
Make it clear that lisp-interaction-mode uses lexical-binding.
* lisp/erc/erc-{button,match}.el (erc-{button,match}-syntax-table):
Omit (, ), and '; as they're not valid nick characters, per RFC 2812
section 2.3.1. This enables correct matching/highlighting of nicks
when they're surrounded by parens, like (nick), and when adjacent to
an apostrophe, like nick's.
* lisp/erc/erc-button.el (erc-button-url-regexp): Use the regexp from
browse-url-button-regexp, which among other things, seems to handle
surrounding pair of parens better.
* etc/NEWS: Announce change to matching color fonts when using XFT.
* src/ftfont.c (ftfont_list) [HAVE_XFT && FC_COLOR]: Query for the
color attribute of the matched font, and skip it if it is not
FcFalse (Bug#37786).
* etc/NEWS: Rearrange and mark entries whether documented or not.
* doc/lispref/streams.texi (Output Variables): Document the new
default of 'print-quoted'.

with the mouse wheel.
* doc/emacs/windows.texi (Window Convenience): Document
'global-tab-line-mode'.
* doc/emacs/search.texi (Repeat Isearch, Symbol Search)
(Isearch Yank): Document the new support for numeric arguments in
Isearch commands.
(Special Isearch): Document 'M-s M->' and 'M-s M-<'.
(Search Customizations): Document 'isearch-lazy-count'. Improve
indexing.
(Not Exiting Isearch): Document the new value of
'isearch-allow-scroll'.
* doc/emacs/maintaining.texi (Xref Commands): Document the new 'g'
key binding.
* doc/emacs/package.texi (Package Installation): Document changes
in 'package-check-signature'.
* doc/emacs/maintaining.texi (VC Change Log): Document
'vc-log-search'.

'dired-vc-rename'.
* etc/NEWS:
* lisp/comint.el (comint-password-function): New variable.
(comint-send-invisible): Use it.
* test/lisp/comint-tests.el (comint-test-no-password-function,

Vclear_message_function is a function.
* src/xdisp.c (set_message): Call Vset_message_function when it's a function.
(clear_message): Call Vclear_message_function when it's a function.
(syms_of_xdisp): New variables set-message-function and clear-message-function
(bug#38457).
* lisp/files.el (backup-by-copying-when-privileged-mismatch): In addition
to checking the file uid, a second test is added: if the file gid is not
greater than backup-by-copying-when-privileged-mismatch,
backup-by-copying-when-mismatch will also be forced on.
* doc/emacs/files.texi, doc/lispref/backups.texi: Updated documentation.
Also fixed a typo in the Emacs reference manual, changing "higher" to
"no greater" so that the limit is no longer documented reversed.
* lisp/progmodes/python.el (python-shell-send-statement): New function.
(python-mode-map): Bind it to key "C-c C-e", and define a python-menu
item for it. (Bug#38426)
* src/process.c (syms_of_process) <read-process-output-max>:
New variable.
(read_process_output): Use it instead of the hard-coded
constant 4096. (Bug#38561)
