`erc-stamp--current-time' instead of the `erc-ts' property to convey
an overriding time value for `erc-add-timestamp'.  Set

dispatch, which test cases rely on for delivering correct timestamp
values in varied contexts.

variable for overriding `insert'.

insert line specially.

Remove unnecessary assertion added 2 days ago

assertion.  It triggers, for no good reason, when running the
recipe of bug#66922 and typing C-p in the *Warnings* buffer after
the recipe finishes, because the glyph passed to this function is
a STRETCH_GLYPH, not a CHAR_GLYPH.

MH-E testing: find locally-installed GNU Mailutils libraries

* test/lisp/mh-e/test-all-mh-variants.sh: LD_LIBRARY_PATH is sometimes

Suggest alternative reason for ERT test duplication error

* lisp/emacs-lisp/ert.el (ert-set-test):
Amend error message; maybe the redefinition was caused by a file
loaded twice (bug#66782).

Suggested by Xiyue Deng.

Round underline position and thickness

* src/sfntfont.c (sfntfont_open): Round underline thickness
instead of truncating it, as is proper according to several
inquiries.

Avoid moving point while analyzing text conversion

* lisp/simple.el (analyze-text-conversion): If neither calling
p-s-i-h nor calling p-t-c-h yields a change to point, return it
to its location before analyze-text-conversion was called.

* src/keyboard.c (kbd_buffer_get_event): See that text
conversion events are uniformly delivered prior to keyboard

ERC 5.6 and introduced by c68dc778 "Manage some text props for ERC
insertion-hook members".  Also, `save-excursion' when narrowing to
prevent point from being dislodged after submitting input at the
prompt.
(erc-insert-timestamp-left-and-right): Don't initialize date stamps
when `erc-timestamp-format-left' is nil or consists only of newlines,
and enable fallback behavior in such cases on behalf of users without
informing them.  Allow global hook members to run first so that those
owned by `scrolltobottom' and similar can see the unadulterated input.
Fix wrong hook name.

repetition, eliminating a Relint complaint.

above, and use the correct submatch this time.  Remove unnecessary and
incorrect second regexp matching.
