Instead of doing a check every time round the loop when it is useful
only the first time, duplicate a bit a code and do the check and its
related action beforehand.
Also, improve some comments.
Also, find_bracket_match() is only called when there is a bracket under
the cursor, so stepping forward will never go beyond the end-of-line,
so the central loop does not need to check for that.
Also, improve a comment and shorten another, change a 'for' to a 'while'
(as the end point is not known), and rename a parameter from a single
letter to a word.
Some of these directives are now colored in their entirety, while for
a few others it's still just the keyword itself that is colored.

The reading order must be predictable, otherwise things might get
colored differently from system to system.

Otherwise the user could do something like
^R^X sed -i 's/a/surprise!/g' name-of-current-file <Enter>
and the file being viewed would be modified anyway.
The word "buffer" in relation to undo has been confusing to translators.
Also, drop the exclamation mark, as there is nothing important or urgent
about these messages.
The keystrokes are recognized and acted upon, but they are not visible
in the menu nor in the help text, and they cannot be rebound. They are
there just to avoid frustrating the muscle memory of long-time users.

Because somehow something goes wrong when SIGWINCHes are handled while
reading from a pipe.
This fixes https://savannah.gnu.org/bugs/?56011.
Bug existed since version 2.4.2, commit 75d64e67.
Some commands can take a little while to execute; showing just the prompt
during that time could give the impression that nothing is happening.
This addresses https://savannah.gnu.org/bugs/?56041.
The lack of initialization caused a nasty bug on some targets (such as
ARMv7) which would make it so that ^S would just say "Cancelled".
While x86 (both 64 and 32 bits) seems to initialize 'response' to zero or
a positive number, ARM does not, and there is usually a negative value in
its place, which triggers the 'if (response < 0)' check and, as a result,
the code says "Cancelled".
This fixes https://savannah.gnu.org/bugs/?56023.

When nano was configured with --enable-tiny --enable-speller, the
block_sigwinch() function should be available, to mask SIGWINCHes
during a spell check.
