* lisp/language/misc-lang.el (composition-function-table): Reorder
Arabic composition rules in descending order of lookback.
* src/composite.c (syms_of_composite): Document the order of rules
in 'composition-function-table'.
* lisp/progmodes/project.el (project--ensure-file-exists): Remove.
(project--read-project-list): Set 'project--list' to nil when the
project list file doesn't exist.
(project-compile): Add args and interactive spec like in 'compile'.
(project-switch-commands): Bind project-vc-dir to "v",
project-shell to "s", and rebind project-find-regexp from "s" to "r".
* doc/emacs/maintaining.texi (Project File Commands):
Describe project-vc-dir and project-shell.
For discussion of the autoloaded function declaration, see
https://lists.gnu.org/archive/html/emacs-devel/2020-05/msg00910.html.
* lisp/dnd.el (dnd-handle-one-url): It is no longer necessary to
declare the autoloaded function browse-url-select-handler after
ldefs-boot.el was updated.
* lisp/progmodes/elisp-mode.el: Declare xref.el function to silence
byte-compiler.
* lisp/progmodes/xref.el (xref-backend-apropos): Rename this
generic's second arg to PATTERN, to clarify that it should be
handled entirely in the backend, with no pre-processing by the
command.
(xref-find-apropos): Update accordingly, but keep compatibility
with backends in older Emacs versions.
(xref-apropos-regexp): Extract from xref-find-apropos.
* lisp/progmodes/etags.el (xref-backend-apropos): Use it here.
* lisp/progmodes/elisp-mode.el (xref-backend-apropos): And here.
Make the navigation in the occur buffer closer
to the navigation in the compilation buffer.
Add bindings to navigate the occur matches (Bug#39121).
Honor `next-error-highlight' and `next-error-highlight-no-select'
when navigating the occurrences.
* lisp/replace.el (occur-highlight-regexp, occur-highlight-overlay):
New variables.
(occur-1): Set `occur-highlight-regexp' to the searched regexp.
(occur-goto-locus-delete-o, occur--highlight-occurrence): New defuns.
(occur-mode-display-occurrence, occur-mode-goto-occurrence):
Use `occur--highlight-occurrence'.
(occur-mode-map): Bind n to `next-error-no-select'
and p to `previous-error-no-select'
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
Announce this change.
* test/lisp/replace-tests.el (replace-tests-with-highlighted-occurrence):
Add helper macro.
(occur-highlight-occurrence): Add test.
* lisp/tab-bar.el (switch-to-buffer-other-tab): Use
'window-normalize-buffer-to-switch-to' on 'buffer-or-name',
like does 'pop-to-buffer' used by 'switch-to-buffer-other-frame',
instead of raising the error "Invalid buffer" on a non-existent buffer name.
This fixes the use case when, for example, 'find-file-hooks'
fails.
* lisp/files.el (find-alternate-file): If buffer 'oname' exists,
kill it before renaming the new one. (Bug#41359)
(calculate-lisp-indent): To distinguish code and data when indenting,
introduce the convention that a space between an open paren and
a symbol indicate that this should be indented as a simple data list.
* lisp/ido.el (ido-make-buffer-list-1):
Create a buffer-local binding to improve performance when a lot of
buffers are open (bug#41029).
Copyright-paperwork-exempt: yes
The existing ITRANS scheme did not support some characters and
language quirks like 'chillu's. The Inscript method had errors.
* lisp/language/ind-util.el (indian-mlm-base-table): Add archaic
chars, Mozhi combos; cleanup.
(indian-mlm-mozhi-table): New scheme Mozhi.
* lisp/leim/quail/indian.el (inscript-mlm-keytable): Correct
errors. Add Inscript chillus & zero-width chars, Mozhi scheme.
* etc/NEWS: Mention the changes.
* lisp/international/mule.el (define-coding-system):
Require :pre-write-conversion and :post-read-conversion functions
to leave the match data untouched.
* src/coding.c (Fdecode_coding_string, Fencode_coding_string):
Document functions as match-data-preserving.
