A short allows for more than 32 thousand values, and the maximum number
of multiline regexes in any of the current syntaxes is... just four.
Reshuffle it to the beginning also because it is used the most often.
Also, tell the terminal to switch on bracketed-paste mode, and toggle
a boolean when the start and stop sequences of such a paste are seen.
This boolean can later be used to suppress auto-indent and such.

The word "fixer" sounds too much as if the command would be able
to fix mistakes or correct errors. Especially when seen next to
"linter", it sounds as if one does a syntax check and the other
fixes the found mistakes. (Although the command might in theory
be used for this, it is not its intended purpose.)
The command can be used to run some kind of formatter or corrector or
arranging tool on the buffer. By default the command is bound to M-F.
The formatter/corrector/arranging program must be non-interactive.

The nano.h file is included only by proto.h, and the proto.h file is
included just once by each src/*.c file. The include guards for these
two header files serve no purpose.
(Include guards are useful when you have bunches of header files
and several of them include others from amongst themselves.)
In this way the keycode cannot be unbound from the 'indent' function,
so pressing <Tab> on a marked region will always indent the region.
This fixes https://savannah.gnu.org/bugs/?56960.
Bug existed since the "tabbing" of a marked region was introduced,
in version 2.9.2, commit 09958ebd.
The 'tabgives' command is syntax-specific and should be followed by a
string containing the character(s) that a single press of the <Tab> key
should produce -- most likely a single TAB or a small bunch of spaces,
but any string is allowed. This overrides the 'tabstospaces' option.
When one wants to make sure <Tab> inserts always four spaces and never
a TAB when editing a Python file, one could add to one's nanorc:
extendsyntax python tabgives " "
where there are four spaces between the quotes. And when one wants
to ensure, when editing a Makefile, that <Tab> always inserts a TAB
and never spaces, independent of what tabstospaces is set to, one
could add to one's nanorc:
extendsyntax makefile tabgives " "
where there is a literal TAB character between the quotes.

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.
Bug existed since commit cba9d8d0 from a month ago.
This "holder" information is needed for every cut and paste and other
block operation. Instead of allocating and freeing it for every such
operation, just have the six elements as static variables. This saves
a little churn, and saves having to declare a type that is used just
once. Plus, the access to these variables will be a little quicker.
When a syntax gets parsed, store the compiled color regexes right away,
instead of compiling them a second time in color_update().

The sphere, the holder, is everything *around* the partition;
it was confusing to call this holder type 'partition'.
Also correct and improve some comments.
When parsing an included syntax file, stop reading when a command other
than 'syntax', 'header' or 'magic' is encountered. The syntax file is
fully parsed the first time that a file needs it. Each 'extendsyntax'
command is stored for unloaded syntaxes and applied after the syntax
is loaded.
Closing a buffer does not unload the syntax, even if no longer used by
another buffer.

The 'cutbottom' variable is only ever used when cutting or copying
consecutive lines: for appending the current line to the already
existing lines in the cutbuffer. As soon as some other operation
is performed, 'cutbottom' becomes irrelevant, it could be set to
anything, it doesn't matter: the pasting of the cutbuffer does not
use the value of 'cutbottom', nor does any other operation.
Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.
You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.
In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

For relatively inexperienced users (as most users of nano probably are)
it is far better that nano produces POSIX text files by default, where
each line ends with a newline character. This means that these files
will "print" properly (not gluing the next prompt at the end of the
last line), tools will see and process each line of them, and, while
editing, adding text at the end is easier.
This addresses https://savannah.gnu.org/bugs/?55997.
