* lisp/progmodes/project.el (project-try-vc): Do not treat a Git
submodule as a project root, go up to the parent repo.
(project--git-submodules): New function.
(project--vc-list-files): Use it.  Recurse into submodules.

* doc/emacs/buffers.texi (Buffers): Say that buffers are killed
when no longer needed.  Suggested by Jean-Christophe Helary
<jean.christophe.helary@traduction-libre.org>.

* lisp/progmodes/xref.el (xref--collect-matches):
Don't call find-buffer-visiting on remote file names, it's pretty
slow (bug#34343).

* lisp/emacs-lisp/bytecomp.el (byte-compile-get-constant):
Use eql for looking up constants instead of eq, allowing
for bignum and flonum deduplication (bug#38708).

* src/minibuf.c (read_minibuf): Fix formatting of an error
message.  Reported by martin rudalics <rudalics@gmx.at>.

* lisp/net/tramp-adb.el (tramp-adb-prompt): Use 'regexp' instead
of 'string' as type for values that are regexps in defcustom
declarations.

* admin/nt/dist-build/build-zips.sh: Ensure that NSIS build always
  uses the actual build number to locate its files.

* admin/nt/dist-build/build-dep-zips.py: Emacs major version number.

  information.

from while loop.

* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Treat all expressions in the body of 'while' as for-effect,
since their values are discarded.  This also finds some errors.

* lisp/woman.el (woman-manpath-man-regexp)
(woman-imenu-generic-expression):
Use 'regexp' instead of 'string' as type for values that are regexps
in defcustom declarations.

* lisp/dired-aux.el (dired-do-find-regexp): Speed up (bug#36857).
Previously, 'find' was called for every marked file (for plain
files and directories both).  Now 'find' is only called for
directories.

* lisp/progmodes/project.el (project--find-regexp-in-files):
Support remote files (bug#34343).

* doc/lispref/internals.texi (Module Functions): Document some
restrictions for module functions.

'module-load' most likely doesn't do what users expect.  Users should
use 'load' and its wrappers, which do the right thing.

* doc/lispref/loading.texi (Dynamic Modules): Document
disadvantages of 'module-load' and recommend normal 'load' and
its wrappers instead.

* doc/lispref/internals.texi (Module Functions): Recommend
'load' over 'module-load'.

* doc/lispref/internals.texi (Module Misc): Simplify example for how
to call 'intern'.  There's no need to pass the optional argument
explicitly.

Previously module authors had to define type aliases for module
functions and finalizers themselves.  This commit adds and documents
aliases so that this is no longer necessary.

* src/emacs-module.h.in: Add 'emacs_function' and 'emacs_finalizer'
type aliases.

* src/emacs-module.c: Remove old 'emacs_subr' and 'emacs_finalizer'
type aliases.
(struct Lisp_Module_Function, module_make_function): Switch from
'emacs_subr' to 'emacs_function'.

* doc/lispref/internals.texi (Module Functions): Document and use
'emacs_function' type alias.
(Module Values): Document 'emacs_finalizer' type alias.

* etc/NEWS: Mention change.

* src/xfns.c (x_get_net_workarea) [!HAVE_GTK3]:
Define in this case too, since x_get_monitor_attributes_fallback
contains a call to it regardless whether HAVE_GTK3 is defined.

Doing so breaks icomplete-forward-completions and
icomplete-backward-completions.

* lisp/icomplete.el (icomplete--sorted-completions): Don't always
resort.

Besides the adverse effect of delaying completions, it tripped up the
useful logic of icomplete-force-complete-and-exit in the case where a
default was available, but no completions calculated yet.

* lisp/icomplete.el (icomplete-fido-ret): Don't force calculation
of completions.

* lisp/icomplete.el (icomplete--sorted-completions): Use
completion--cache-all-sorted-completions.
