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.

This is needed to implement the demand loading of syntax files, as any
errors that these files may contain would otherwise overwrite things on
the screen and the messages wouldn't be on the terminal when nano exits.
It also allows nano to start up on a Linux console when there are errors.

The integrated spell checker does not use regular expressions, and
'refresh_needed' is set to TRUE anyway, so the tidy_up_after_search()
call there is effectively a no-op.
All extractions are done into the cutbuffer, so it is pointless to pass
'cutbuffer' and 'cutbottom' in and back out as parameters all the time.
Just use those global variables directly.
Also, rename the function as there is no longer a buffer among its
parameters.
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.

When nano was configured with --enable-tiny --enable-speller, the
block_sigwinch() function should be available, to mask SIGWINCHes
during a spell check.
Somehow a SIGWINCH pushes nano past the wait() in do_alt_speller(),
even though the external spelling program hasn't finished.
This fixes https://savannah.gnu.org/bugs/?56010
by reverting commit 1f39f60b.
Bug existed since version 3.2.
Option -J (--guidestripe) takes a column number as argument and then
shows a vertical, colored bar over the entire height of the buffer,
to aid the user in regulating the width of the text when the terminal
is wider than this desired width.

All tested systems (FreeBSD, NetBSD, OpenBSD, Alpine, and Ubuntu)
support the GNU-style word boundaries (\< and \>), either natively
or through using the regex module from gnulib.
If this change breaks regexes containing \< or \> on your system,
please report a bug: https://savannah.gnu.org/bugs/?group=nano

Not stepping beyond the last line of the paragraph means that the
length of the paragraph is always the difference in line numbers
(between first and last line of the paragraph) plus one.
