8c7b6bd21a tweaks: when precalculating, allocate all the cache space upfront 
Instead of doing it haphazardly while lines are getting categorized.

21d0755de5 tweaks: try the allocation of a multidata cache just once per line 
It does not need to be allocated for each multiline regex separately.

345cf5accc files: don't close a newly-created buffer when it is the only one 
This fixes https://savannah.gnu.org/bugs/?56504.
Reported-by: Liu Hao <lh_mouse@126.com>

Bug existed since commit 7e422402 from two weeks ago.

c7ca60b046 tweaks: don't check the user's nanorc file for accessibility twice

01e4f85f29 tweaks: remove a check that is no longer relevant 
Since commit 7028adf2 from three days ago, also the color commands of
syntaxes that are defined in a main nanorc will get parsed during a
second pass, so it is perfectly possible to extend such syntaxes
later on in the same (or another) nanorc file.

6bfbb2bcd9 tweaks: remove two more unneeded assignments 
'opensyntax' is relevant only during the first pass through all the
nanorc files (intros_only == TRUE) when it is checked that syntax
commands are grouped properly and not mixed with others.  And
'lastcolor' is relevant only during the second pass of a specific
syntax, because only then the color commands are actually parsed.

d82c753ba4 rcfile: at terminating points, verify that a defined syntax is not empty 
Whenever, in an rcfile, a command is encountered that is not part of a
syntax definition, a currently open syntax should be closed, but only
after checking that the syntax contains at least one color command.

This fixes https://savannah.gnu.org/bugs/?56501.

Bug existed since version 2.3.3.

0af9ce926b rcfile: close off a syntax when a non-syntax command is encountered 
The 'color' commands of a syntax definition should not be allowed to
be interspersed with other, non-syntax commands.

This fixes https://savannah.gnu.org/bugs/?56498.

Bug existed since before version 2.6.0.

accd17c249 tweaks: remove four unneeded pre-processor directives

anymore since commit ecd18c16, more than two years ago.

e8eb30cad6 tweaks: just mark four rcfile errors for translation, like the others 
The messages get translated when they get stored in the linked list.
This is to economize on the number of actual calls of gettext().

19f71632c8 tweaks: remove an unneeded "closing" of a syntax after extending it 
As 'extendsyntax' commands are no longer interpreted immediately when
the rcfiles are read, there is no need to set 'opensyntax' to FALSE
after interpreting such a command -- for a single syntax they are all
interpreted in a row.

e3f18e7a6c tweaks: rename two variables, and frob some comments

7028adf211 rcfile: fully read each included file, so all its syntaxes are seen 
An included file can contain multiple syntaxes.  If reading would stop
as soon as a command different from 'syntax' and 'header' and 'magic'
is found, any later syntaxes would not be seen.  So each nanorc file
needs to be fully scanned -- it's just the interpretation of all the
color commands that we want to delay until the syntax gets actually
used.

This fixes https://savannah.gnu.org/bugs/?56478.

c57d040e99 tweaks: don't bother calling mblen() in a non-UTF-8 build 
There is no need, because in non-UTF-8 encodings nano treats
each single byte as one character anyway.

0adb15c7a1 display: properly show all characters in a non-UTF-8 build 
Also, don't use mblen() directly, to not get stuck when it returns -1,
which it will when running a non-UTF-8 build in a UTF-8 locale.

This fixes https://savannah.gnu.org/bugs/?56472.

ed40fd8031 tweaks: reorder some code, to further optimize display_string() for ASCII 
The majority of characters in the files that get edited with nano will
be single-byte printable ASCII characters, so their case should come
first in the main loop of display_string().

cd09482231 tweaks: elide a function that is an amalgam of three others 
In addition, the function was used just once, had a weird return value,
and now some more code can be excluded from a non-UTF8 build.

Make use of the fact that any single-byte character always occupies
just one column, and call the costly mbtowc() and wcwidth() only for
characters that actually are multibyte.

1075de1222 tweaks: rename two functions, to get rid of the "mb" abbreviation 
Also, for me "move" is about moving the cursor.  But these functions
