the image, and that captions be no longer than 50 chars and do not end
in `.'. Follow those rules.
* etc/emacs.metainfo.xml: Note that Emacs is best with a keyboard, but
other forms of input are possible. Also note that Emacs can access the
Internet. A modestly sized display is sufficient.

Previously, flymake-indicator-type defaulted to either fringes
or margins. But fringes should be used on graphical frames, and
margins on TTY frames. So default to fringes instead, and
simply fall back to margins automatically on text frames.

fringes. (bug#77313)
(flymake-mode): Fallback to margins if there's no fringes.

when it's non-nil.
(treesit-toggle-sexp-mode): New command.

checking that all files are in compatible VC states. In
particular, consistently return 'edited' when all files are
either added, removed or edited, instead of allowing the return
value to depend on the order of the files in VC-Dir, and offer
to registered unregistered files if doing so would allow the
operation to proceed.

(vc-next-action): Replace call to vc-compatible-state.
Document, in this command's docstring, the new feature
implemented in vc-only-files-state-and-model.

This macro is useful when making repeated use of a structures accessor
functions, such as reading from a slot and then writing to a slot. It
is similar to 'with-slots' from EIEIO, but uses accessor functions
instead of slot names.
* lisp/subr.el (replace-buffer-contents): Don't obsolete
function. Its purpose is to serve as a command and such
obsoletion was unnecessary to begin with.
Swap the role of `replace-region-contents` and `replace-buffer-contents`,
so `replace-region-contents` is the main function, implemented in C,
and `replace-buffer-contents` is a mere wrapper (marked as obsolete).
Also remove the need to rely on narrowing and on describing the
new text as a function.
Finally, allow MAX-SECS==0 to require a cheap replacement, and
add an INHERIT argument.
* src/editfns.c: Include `coding.h`.
(Freplace_region_contents): Rename from `Freplace_buffer_contents`.
Change calling convention to that of `replace-region-contents`.

* test/src/editfns-tests.el (replace-buffer-contents-1)
(replace-buffer-contents-2, replace-buffer-contents-bug31837):
Use `replace-region-contents`.
(editfns--replace-region): Delete.

Adds tests for new types of SOURCE args.
