A compatibility digraph characters, such as Dž, are neither upper- nor
lower-case. At the moment however, those are reported as upper-case¹
despite the fact that they change when upper-cased.
Stop checking if a character is upper-case before trying to up-case it
so that title-case characters are handled correctly. This fixes one of
the issues mentioned in bug#24603.
¹ Because they change when converted to lower-case. Notice an asymmetry
in that for a character to be considered lower-case it must not be
upper-case (plus the usual condition of changing when upper-cased).
* src/buffer.h (upcase1): Delete.
(upcase): Change to upcase character unconditionally just like downcase
does it. This is what upcase1 was.
* src/casefiddle.c (casify_object, casify_region): Use upcase instead
of upcase1 and don’t check !uppercasep(x) before calling upcase.
* src/keyboard.c (read_key_sequence): Don’t check if uppercase(x), just
downcase(x) and see if it changed.
* test/src/casefiddle-tests.el (casefiddle-tests--characters,
casefiddle-tests-casing): Update test cases which are now passing.
Use Unicode data to generate case tables instead of mostly repeating
them in lisp code. Do that in a way which maps ‘Dz’ (and similar)
digraph to ‘dz’ when down- and ‘DZ’ when upcasing.
https://debbugs.gnu.org/cgi/bugreport.cgi?msg=89;bug=24603 lists all
changes to syntax table and case tables introduced by this commit.

comment starter (Bug#24870).
* src/syntax.c (in_2char_comment_start): New function, extracted from
`scan_sexps_forward'.
(scan_sexps_forward): Add check for a 2-char comment starter before the

character index. Move the single char comment syntax cases into the
switch instead of special casing them before.
* test/src/syntax-tests.el (parse-partial-sexp-paren-comments):
(parse-partial-sexp-continue-over-comment-marker): New tests.
'let' and 'let*' document that their first argument has to be a list,

setting to nil is now supported.
(ffap--gopher-var-on-line): New function.
(ffap-gopher-at-point): Use it instead of the old ffap-gopher-regexp

thread is alive before waiting for it to become blocked on the
conditional variable.

attempting to lock the mutex, to make sure the lock's owner is
recorded correctly.

the emacs-buildstatus list. (Bug#24503)
