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
This addresses https://savannah.gnu.org/bugs/?55207.
When the palette is getting initialized, it is too late to send any
error messages about the rcfile options to standard error.
This fixes https://savannah.gnu.org/bugs/?52871.

Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab. The intended tab size (for keeping most lines
within 80 columns) is now four.
Adding the obscure A_PROTECT attribute to every color prevents an
occasional miscoloring of the first few rows on the screen -- when
ncurses is version 6.0 and dates from before October 17, 2015.

This avoids https://savannah.gnu.org/bugs/?49912 while at the same time
avoiding to draw the edit window twice in a row -- the first drawing
would use a wrong margin, which results in a visible and irritating
shift left or right of the content upon the second drawing.
This fixes https://savannah.gnu.org/bugs/?50877.
The interval 2013-2017 for the Free Software Foundation is valid
because in those years there were releases with changes by either
Chris or David, and the GNU maintainers guide advises to mention
a new year in all files of a package, not just in the ones that
actually changed, and be done with it for the rest of the year.
When replacements are made, nothing needs to be reset any more
(it was done insufficiently anyway). Just make sure the screen
is refreshed when all is done -- this may be superfluous when
doing interactive replacements, but not when replacing all.
When painting a line, the multidata of the line /before/ it is valid
in most cases: it was determined just a moment ago. And it tells us
all we need to know: whether there is an unpaired start match before
the current line or not.
The only exception is when painting the first line of the screen:
the multidata of the line before it might be stale. So for the
first screen line we will always have to do some backtracking.
But that is left for later.
This fixes https://savannah.gnu.org/bugs/?50121.
Just assign the 'CNONE' value upfront, instead of figuring out
at the end of the line whether anything has been assigned yet.
Also, the old logic would leave unmarked a line that contains a
start match without any terminating end match. Not serious, but
not right.
Don't blithely overshoot the end of a line when both start regex and
end regex match an empty string. Overshooting would let the matching
run on into uncharted country and thus ultimately cause a segfault.
This fixes https://savannah.gnu.org/bugs/?50056.

Also, compose the coloring attributes during initialization
instead of every time when painting something.
