* lisp/emacs-lisp/copyright.el (copyright-find-copyright): Make
the double check also work when searching from the end (bug#7179).
Do not merge to master.
* lisp/eshell/em-extpipe.el (eshell-parse-external-pipeline): Fix
misinterpreting sharp-quoted symbols as the beginning of single-quoted
strings (Bug#53518). Add protection against a possible infinite loop.
* test/lisp/eshell/em-extpipe-tests.el (em-extpipe-test-17): New
test (bug#53518).
* src/haikumenu.c (Fhaiku_menu_bar_open): Get draw lock before
updating the menu bar.
* src/haikuterm.c (haiku_read_socket): Don't update menu bar if
b->no_lock.
* lisp/vc/add-log.el (change-log-fill-file-list): New function to
improve how we fill all-file-name ChangeLog lines (bug#19341).
(change-log-indent): Use it.
* lisp/emacs-lisp/comp.el (batch-native-compile): Add return
value.
(batch-byte+native-compile): Touch the produced .eln after the
corresponding .elc is produced.
Split the C auxiliary function `concat` into separate functions for
string and list/vector as target types, respectively. This makes them
simpler and faster.
Implement `Fcopy_sequence` more efficiently for strings, lists and
vectors instead of using `concat`.
The result is a significant performance increase for the Lisp
built-ins concat, append, vconcat, copy-sequence and anything using
them such as mapconcat, copy-alist and propertize.
* src/fns.c (concat2, concat3, Fconcat): Use concat_strings.
(Fappend, Fvconcat): Adapt to changed signature of concat.
(Fcopy_sequence): Faster implementation for lists, strings, and vectors.
(concat_strings): New.
(concat): Strip code for string target, simplify, optimise.
(Fcopy_alist): Use Fcopy_sequence.
This is necessary for preserve the original arguments to forward on to
:external commands. Previously, when :preserve-args was also set, the
original argument list could be altered, changing the meaning of the
command.
* lisp/eshell/esh-opt.el (eshell-eval-using-options): Copy MACRO-ARGS
when :preserve-args is set, and pass the original value to
'eshell--do-opts'.
(eshell--do-opts): Use the original arguments when calling an external
command.
* lisp/eshell/em-tramp.el (eshell/su, eshell/sudo): Don't copy the
original arguments, since 'eshell-eval-using-options' does this for
us.
* test/lisp/eshell/esh-opt-tests.el (esh-opt-process-args-test):
Split this test into...
(esh-opt-test/process-args)
(esh-opt-test/process-args-parse-leading-options-only)
(esh-opt-test/process-args-external): ... these.
(test-eshell-eval-using-options): Split this test into...
(esh-opt-test/eval-using-options-short)
(esh-opt-test/eval-using-options-long)
(esh-opt-test/eval-using-options-constant)
(esh-opt-test/eval-using-options-user-specified)
(esh-opt-test/eval-using-options-short-single-token)
(esh-opt-test/eval-using-options-terminate-options)
(esh-opt-test/eval-using-options-parse-leading-options-only)
(esh-opt-test/eval-using-options-unrecognized): ... these.
(esh-opt-test/eval-using-options-external): New test.
* test/lisp/eshell/em-tramp-tests.el: New tests.
* src/haiku_support.cc (class EmacsWindow): New fields
`menu_update_cv', `menu_update_mutex' and `menu_updated_p'.
(~EmacsWindow): Destroy cv and mutex.
(MenusBeginning): Release lock and wait for condition to be
become true.
(EmacsWindow_signal_menu_update_complete): New function.
* src/haiku_support.h (struct haiku_menu_bar_state_event): New
field `no_lock'.
* src/haikumenu.c (Fhaiku_menu_bar_open): Always update menu
bar.
* src/haikuterm.c (haiku_read_socket): Always update menu bar
and signal the window thread after update completion.
* lisp/emacs-lisp/cl-generic.el (cl--generic-lambda): `commandp` and
`interactive-form` are for function values, not for source code.
* lisp/cedet/semantic/db-el.el (semanticdb-elisp-sym->tag):
Prefer `commandp` over `interactive-form`.
When using eshell-match-result via eshell-command-result-p to examine
the output of asynchronous Eshell commands, a newly emitted prompt is
included in the text against which the regexp is matched. This makes
it awkward to match against the whole output; for example, to check
whether it is empty. Rework the function to exclude the prompt.
* test/lisp/eshell/eshell-tests-helpers.el (eshell-match-result):
Exclude any newly emitted prompt from the text against which the
regexp is matched. Additionally, the function no longer moves point.
* test/lisp/eshell/eshell-tests.el (eshell-test/flush-output): Update
and simplify test given how eshell-match-result no longer moves point.
