* lisp/progmodes/grep.el (grep-read-files): Cease returning
some completion candidates unconditionally. Use
'completion-file-name-table' over 'read-file-name-internal'
because the latter uses 'completion-table-with-quoting', and
that doesn't blend well with other tables in
'completion-table-merge'.

There are a lot of excluding globs, and checking them all is expensive.
The files glob (i.e. the glob for files we actually want) is usually
just one or two entries, so it's quite fast to check.
If find checks the files glob first and then the excluding glob, it has
to do much less checking (since the files glob will substantially narrow
down the set of files on its own), and find performance is much better.
In my benchmarking, this takes (rgrep "foo" "*.el" "~/src/emacs/trunk/")
from ~410ms to ~130ms.
Further optimizations are possible now that the ignores and matched
files are in the same <F> argument which can be rearranged more easily
without compatibility issues; I'll do those optimizations in later
commits.
* lisp/progmodes/grep.el (rgrep-find-ignores-in-<f>): Add.
* lisp/progmodes/grep.el (rgrep-default-command): Check
rgrep-find-ignores-in-<f> and move the excluded files glob to part of
the "files" argument. (Bug#71179)
grep-find-ignored-files is documented to also include cons
cells, not just globs, but there were two places outside grep.el
where we were using it as if it was only a string list.
To fix this, add a helper function named grep-find-ignored-files
which handles grep-find-ignored-files properly and returns the
list of globs, and use it everywhere.
* lisp/progmodes/grep.el (grep--filter-list-by-dir)
(grep-find-ignored-files): New functions.
(rgrep-find-ignored-directories): Use grep--filter-list-by-dir.

Use grep-find-ignored-files function.
* lisp/dired-aux.el (dired-do-find-regexp):
Use grep-find-ignored-files function.

Use grep-find-ignored-files function, if bound. (bug#71115)
* lisp/progmodes/grep.el (grep-heading-regexp): New user option.
(grep-heading): New face (bug#59888).
(grep--heading-format, grep--heading-state, grep--heading-filter):
Filter function for grep processes and supporting variables.
(grep-use-headings): New user option.
(grep-mode): Use the above, if applicable.
* lisp/progmodes/compile.el (compilation-parse-errors-function): Remove.

(compilation--compat-parse-errors): Remove function, not used any more.
(compilation-error-list, compilation-parsing-end)
(compilation-old-error-list): Remove vars, not used any more.
(compilation-last-buffer): Mark as obsolete (sadly, forgot to do that
back in Emacs-22).
* lisp/textmodes/tex-mode.el: Remove old code that was needed for
Emacs<24.
* lisp/progmodes/prolog.el (prolog-consult-compile): Remove long-dead code.
(compilation-parse-errors-function): Remove declaration, not used any more.
(prolog-parse-sicstus-compilation-errors): Remove function, not used any more.

changes.

This reverts commit 856cd948d1.
Emacs got better at quoting shell arguments and the original value
works correctly for vc-git-grep. At the same time, the value
introduced on that commit caused a regression on lgrep.
* lisp/progmodes/grep.el (grep-files-aliases): Use previous value for
`all'. Fixes bug#52367
* lisp/progmodes/grep.el (grep-compute-defaults):
Don't require "grep --help" to finish with exit status 0 (BSD grep
does not) and check the output in a slightly more robust way.
* lisp/progmodes/grep.el (grep-regexp-alist): Adjust the return value
from the END-COL function by one since it is now (after fixing
bug#49624) inclusive. Found by Juri Linkov.
* lisp/progmodes/grep.el (grep-compute-defaults):
Add '-H' to grep-find-template (bug#48471).
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Pass the root directory name without the trailing slash.
* lisp/progmodes/xref.el (xref-matches-in-directory): Ditto.
* test/lisp/progmodes/xref-tests.el (xref--xref-file-name-display-is-abs)
(xref--xref-file-name-display-is-relative-to-project-root):
Make tests more strict again.
* lisp/progmodes/grep.el (grep-mode-font-lock-keywords):
Adapt regexp to match MS Windows-style shell-quoting.
* test/lisp/progmodes/grep-tests.el: New file.
To scroll up/down the current displayed occurrence/error
without abandon the Occur/Grep buffer.
Add also a command 'recenter-other-window' to recenter
the other window from any kind of buffer.
* lisp/window.el (recenter-other-window): New command.
Bind recenter-other-window to S-M-C-l (Bug#46119).
* lisp/simple.el (recenter-current-error): New command.
* lisp/progmodes/grep.el (grep-mode-map):
Delete bidings for n and p.
* lisp/progmodes/compile.el (compilation-minor-mode-map):
Move here the n and p bindings.
Bind `recenter-current-error' to l.
* lisp/replace.el (occur-mode-map):
Same.
* doc/emacs/windows.texi (Other Window):
* doc/emacs/display.texi (Recentering):
Document recenter-other-window.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
Announce the changes.
* doc/lispref/os.texi (System Environment): Add `path-separator'
function and `null-device' variable and function.
* etc/NEWS: Mention 'null-device' and 'path-separator'. Fix typos.
* lisp/files-x.el (path-separator, null-device): New defuns. (Bug#3736)
* lisp/net/tramp-adb.el
(tramp-adb-connection-local-default-shell-variables): Rename from
`tramp-adb-connection-local-default-profile'.
* lisp/net/tramp-integration.el
(tramp-connection-local-default-system-variables): New defvar.
Add it to connection-local profiles.
(tramp-connection-local-default-shell-variables): Rename from
`tramp-connection-local-default-profile'.
* lisp/progmodes/grep.el (grep-hello-file): New defun.
(grep-compute-defaults): Use `null-device' function for remote
case. Handle remote `hello-file'. Use `process-file-shell-command'.
(grep,grep-expand-keywords, lgrep): Use `null-device' function for
remote case.
* lisp/progmodes/grep.el (grep-expand-template): Add new arg 'more-opts'.
(grep-use-directories-skip): New variable.
(lgrep): Set 'grep-use-directories-skip' to the result of 'grep-probe'.
Use "--directories=skip" when 'grep-use-directories-skip' is t.
* lisp/progmodes/grep.el (lgrep): Do the directory ignores here
(bug#23590).
(grep-compute-defaults): ... instead of here, because this would
affect all grep commands, not just lgrep.
