Don't use completions-first-difference for the 'substring', 'flex' and
'partial-completion' styles, since there can be really no reasonable
definition of a "first" difference there.
Make completions-common-part inherit from 'underline' so that it is
useful by default for all completion styles.
* lisp/minibuffer.el (completions-common-part): Adjust
description and change default value.
(completions-first-difference): Ajust docstring.
(completion-pcm--hilit-commonality): Don't use
completions-first-difference.
This commit re-does the now-reverted commit with the same title. That
version relied on generic functions, which cannot be used yet in files
such as lisp/minibuffer.el. This version uses a symbol property
completion--adjust-metadata instead.
The new facility allows completion styles to have a say in metadata
properties such as cycle-sort-function and display-sort-function.
This is especially useful for completion styles such as 'flex', which
generally produce many matches, including some potentially "obscure"
ones. The default sorting strategy would often bubble the latter to
the top of the list.
The sorting function for 'flex' considers pre-computed matching scores
and is thus much better than the default for this particular style.
Additionally, it overrides the completion table's cycle-sort-function
or display-sort-function properties if they exist, although it still
uses them to pre-sort the result, so that they are still relevant for
resolving ties.
* lisp/minibuffer.el (completion--nth-completion)
(completion--flex-adjust-metadata): New helper.
(flex): Put completion--adjust-metadata property.

completion-adjust-metadata-for-style.

(completion-adjust-metadata-for-style 'flex): New method.
The problem with the original fix for bug#5095 is that it drops
the current event, which is a valid character event and not -2.
Thus, the first ESC character sent by the terminal after turning
on focus tracking is lost and we get '[' and 'I' events separately
inserted into the buffer afterwards.
* src/keyboard.c (read_key_sequence): Add key as mock_input and replay
sequence using new keyboard, when the key is not -2.
The functions image-scroll-down, image-scroll-up, image-next-line, and
image-previous-line now return pixel values instead of multiples of
character height as of commit 9c66b09950.
* lisp/doc-view.el (doc-view-scroll-up-or-next-page):
(doc-view-scroll-down-or-previous-page):
(doc-view-next-line-or-next-page):
(doc-view-previous-line-or-previous-page):

image-next/previous-line now returning pixel values instead of
multiples of character heights. Fixes bug#37874.
* lisp/progmodes/cc-cmds.el (c-guess-fill-prefix): When determining a new
block comment prefix (i.e. there isn't one already there to copy), and that
prefix is hard up against a comment closer, ensure there are at least two
spaces before the closer.
(c-indent-new-comment-line): Amend the strategy for ensuring that point isn't
left hard up against the comment closer after M-j.
* lisp/gnus/gnus-sum.el (gnus-thread-hide-subtree): Make the
"Non-nil" predicate do what it's supposed to (i.e., return non-nil
on non-nil values (excepting predicates)) (bug#37916).
