closing bracket.

40f8ca0d07 syntax: html: colorize only full attributes, and colorize strings later 
Attribute names that are a part of another word should not be colored,
nor should attribute names within strings.

This addresses the other half of https://savannah.gnu.org/patch/?9865.

3c695664ec tweaks: elide a function call for the plain ASCII case 
When dealing with a plain, seven-bit ASCII character, don't bother
calling is_cntrl_mbchar() but determine directly whether it is a
control character.  Also reshuffle things so that we don't compare
charlen == 1 when we already know it is 1.

fa88fcc8f2 tweaks: rename a function, and elide a parameter that is always NULL 
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter.  So, drop that parameter and remove the
chunk of code that handles it.  Also rename the function, as there are
already too many functions that start with "parse".

c2d8641f01 chars: add a faster version of the character-parsing function 
It elides a parameter that is always NULL, and elides two ifs
that always take the same path.

3d5e51bcd0 syntax: nanorc: colorize in bright red everything that is invalid

95ae124891 history: don't wait when there is something wrong with the history files 
Do not wait for the user to press a key when there is some problem
with any of the history files.  Just start and indicate the problem
on the status bar.  The precise error message is stored and will be
shown on the terminal when exiting from nano.

This addresses https://savannah.gnu.org/bugs/?56524.

1a8646393a tweaks: condense a fragment of code by making use of a helper function 
(It copies a byte too many, which then gets overwritten in the next
statement, but this is not speed-critical code.)

46566572d6 utils: don't accept NULL for the string to be copied

b4a5fac744 tweaks: use a literal NULL instead of a variable that is NULL 
Now all calls of mallocstrncpy() have NULL as the first parameter
(apart from one call in utils.c, but that can be changed), so the
function can be simplified.

3a0ac428ba tweaks: remove a redundant check for an existing emergency file 
This case is caught (by O_EXCL) later on, at the appropriate moment:
when the file is created.

Also, this removes a superfluous lstat() for each temporary file.

5390f96900 files: distinguish between read error and write error when prepending 
This fixes https://savannah.gnu.org/bugs/?57066.

Bug existed in this form since version 2.4.3 -- in older versions
it segfaulted.

a6365707c0 tweaks: remove the superfluous closing of a file descriptor

4e40ec057e tweaks: elide an unneeded check when making a backup 
When making a backup, we can be certain that the relevant file
is not a temporary file, so 'stream' will necessarily be NULL.

022cc084a7 files: when opening a file for copying, it should NOT be created 
Weird bug.  The first occurrence is probably never hit because the
existing file has been tentatively opened fourteen lines earlier,
but that looks superfluous: double work.  And the second occurrence
will not be hit because the temp file is unlikely to have disappeared.

0f98466e2f tweaks: adjust the indentation after the previous change 
Also, don't bother assigning the stream pointer of the existing file
to variable 'f', as it gets overwritten right away by the pointer of
the temp file.

40c067133a tweaks: remove two superfluous conditions when prepending 
When prepending, we cannot be writing to a temp file,
so 'stream' (and thus 'f') will necessarily be NULL.

3347682fd0 tweaks: remove a pointless updating of the title bar 
A possible change in filename won't be pushed to the screen until a
doupdate() is done, and that won't happen until nano is waiting for
a keystroke again.  So... just let it be.
