Since tiling window managers may react allergically to resize
requests immediately following MapNotify events on X, make sure
that such requests are issued only when a new frame should not
become visible and a size has been explicitly requested for it.

flag.

(epa-mail-default-recipients, epa-mail-encrypt):
Use rfc822-goto-eoh, not mail-header-separator.

Properties" sub-menu to Text mode menu.

confirmation message asking to kill buffers of deleted dir in the case
where `dired-listing-switches' contain -p (bug#48301).
(font-lock-fontify-syntactically-region): Use `comment-end-skip` as
fallback for `font-lock-comment-end-skip`, as is done for

made unnecessary.

(hexl-find-file): Enhance the doc strings, mainly explaining the
complications of inserting multibyte characters.
(hexl-insert-multibyte-char): Don't treat CH as unibyte if the
coding-system isn't ASCII-compatible. Don't treat null bytes as
multibyte.

* etc/NEWS: Remove the verbose, detailed example of client certificate
specification and refer to the ERC manual instead.

own function, and respect the new variable (bug#47843).

`hack-local-variables'.
(permanently-enabled-local-variables): New variable.
This reverts commit 3d276324ed

It is replaced by commit c233f4eccd
