* lisp/language/indian.el ("Tamil"): Change the default input method
of the Tamil language environment to the new input method.
* lisp/leim/quail/indian.el
(quail-tamil-itrans-compute-syllable-table): New function extracted
from...
(quail-tamil-itrans-syllable-table): ... here. Use the above
function.
(quail-tamil-itrans--consonant-order): Auxiliary variable for the
above function.
(quail-tamil-itrans-compute-signs-table): Add new VARIOUS argument.
(quail-tamil-itrans-various-signs-and-digits-table)
(quail-tamil-itrans-various-signs-table): Adjust call to the above
function.
("tamil-phonetic"): Add new input method.
(tamil-input): New group for the input method.
(tamil-translation-rules): New defcustom for the input method to
change the translation rules.
(tamil--syllable-table, tamil--signs-table, tamil--hashtables)
(tamil--vowel-signs): Internal variables used by the input method.
(tamil--setter, tamil--make-tables)
(tamil--update-quail-rules): Internal functions for the input method.
(bug#56323)
* etc/NEWS: Announce the new input method.
* src/frame.c (delete_frame): Bind `x-auto-preserve-selections'
to nil if deleting display.
* src/xselect.c (x_clear_frame_selections): Pass original frame
to that function.
* src/xterm.c (x_preserve_selections): Fix determining the new
owner.
(syms_of_xterm): New defsym `x-auto-preserve-selections'.
* src/xterm.h: Update prototypes.
* doc/emacs/files.texi (Image Mode): Adjust documentation.
* lisp/image/image-converter.el (image-convert): Let the converter
know whether it's a file or not.
* doc/emacs/files.texi (Image Mode): Document it.
* lisp/image/image-converter.el (image-converter-add-handler): New
function (bug#48415).
(image-convert): Use it.
* lisp/pcmpl-unix.el (pcomplete/rlogin, pcomplete/rsh): Make into
aliases for 'pcomplete/ssh', as "rsh" and "rlogin" is more often than
not aliases for "ssh" on modern machines.
In particular, this resolves an issue where '$+' referenced the real
environment variable '$PWD' instead of the Eshell variable alias of
the same name. This meant that changing directories in Eshell
wouldn't update the value of '$+'.
* lisp/eshell/esh-var.el (eshell-get-variable): Allow Eshell variable
aliaes to point to other aliases.
* test/lisp/eshell/em-dirs-tests.el (em-dirs-test/pwd-var)
(em-dirs-test/short-pwd-var): Adapt tests to check this case
(bug#56509).
* lisp/eshell/em-dirs.el (eshell-inside-emacs)
(eshell-dirs-initialize): Move 'INSIDE_EMACS' from here...
* lisp/eshell/esh-var.el (eshell-inside-emacs)
(eshell-variable-aliases-alist): ... to here, and improve doc string.
* test/lisp/eshell/eshell-tests.el (eshell-test/inside-emacs-var):
Move from here...
* test/lisp/eshell/esh-var-tests.el (esh-var-test/inside-emacs-var):
... to here.
(esh-var-test/last-arg-var-indices)
(esh-var-test/last-arg-var-split-indices): New tests.
* test/lisp/eshell/em-alias-tests.el:
* test/lisp/eshell/em-dirs-tests.el:
* test/lisp/eshell-em-script-tests.el: New files.
* doc/misc/eshell.texi (Built-ins): Fix 'cd' documentation; it works
with the directory ring, not the directory stack. Move built-in
variables documentation from here...
(Variables): ... to here, and add documentation for missing built-in
variables.
* src/buffer.c (Fmake_indirect_buffer): Kill the local
buffer-stale-function variable instead of setting it
buffer-locally to the default value. This should have the same
effect, but is less confusing.
* doc/misc/cl.texi (Lists, List Functions, Efficiency Concerns): Don't
mention 'cl-cXXXr' compatibility aliases for built-in 'cXXXr'
functions. They shouldn't be used in new code.
* lisp/files.el (remote-shell-program): Default to "ssh" only. The
other commands in this list have severe security issues, and it is
easy enough for users to customize them manually if they want to.
See also the discussion in: https://debbugs.gnu.org/56461
* lisp/play/gomoku.el (gomoku-X): Use blue rather than green for
crosses on bright background for better legibility.
(Red for naughts could be adjusted but seems just about bearable.)
This fixes bug #56502. That function and these variables were manipulated by
the former file emacs-lisp/lmenu.el that was finally expunged from directory
obsolete/ by Stefan Kangas on 2020-05-15. There remain references to them in
the *.c, and *.m files.
* src/keyboard.c (syms_of_keyboard): Remove declarations of the symbol and
variable.
* src/haikumenu.c (set_frame_menu_bar)
* src/keyboard.c (command_loop_1)
* src/nsmenu.m (ns_update_menubar)
* src/pgtkmenu.c (set_frame_menubar)
* src/xdisp.c (update_menu_bar)
* src/xmenu.c (set_frame_menubar): Remove calls to Qrecompute_lucid_menubar
contitional on Vlucid_menu_bar_dirty_flag.
* src/minibuf.c (minibuf_conform_representation): Remove.
(Ftry_completion): Don't call it.
(Ftest_completion): Don't use the obsolete Fstring_make_unibyte or
Fstring_make_multibyte; they don't serve any useful purpose here.
We don't try to equate unibyte and multibyte raw bytes in symbol
lookups elsewhere and there is no reason to do it here.
