When completion-ignore-case is non-nil, if all completions share
a common prefix ignoring case, try-completion has always
returned that.  Now, if all completions also share a common
prefix including case, try-completion includes that common
prefix in its return value (bug#79377).

* lisp/minibuffer.el (completion-pcm--merge-completions): Always
use return value from try-completion, which may change case.

which changes case.

(elisp-scope--match-spec-to-arg): Add new 'list', 'and', and
'plist-and-then' parametric specs, and add 'widget-type' as a
new recursive spec.

* test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el
Add test.

Rename a couple of faces to solidify the convention that the
face name 'elisp-foo' implies "references to foo", not "foo
definitions".  For definitions we use 'elisp-deffoo' if foo is
only one word, or 'elisp-bar-baz-definition' otherwise.

Rename to 'elisp-function'.

Update references to renamed faces.

`tramp-archive-run-real-handler' for testing existence of
`archive'.  (Bug#79582)
