This function is used in get_totsize(), so speed is important.
There is no reason why the length of the string must limited to a
certain size -- that is just a leftover from the function merge in
commit ba2e6f43 from a year ago.
The use of a double dash (for an option name or as sentence separator)
is too common to allow it to be seen always as a comment introducer.
Users of Lua and Postgres will have to redefine 'quotestr' themselves
if they want to be able to rewrap block comments with ^J.
The other characters that were added in commit c5a72103 (!, %, and ;)
are less problematic because they tend to be glued to the end of words,
so they are unlikely to appear at the start of a line.
This fixes https://savannah.gnu.org/bugs/?56462,
and fixes https://savannah.gnu.org/bugs/?56461.
Bug existed since version 4.0, commit c5a72103.
There is no need to make a copy of the line, because if there are some
bytes that are moved, they are always moved toward the left -- the line
can only shrink, never expand.
When squeezing excess spaces from a line has proved unsuccessful, we
have already copied all of its data, so it hardly makes a difference
whether we free the old or the new data. Choose to free always the
old data, so that we can simplify things.
Instead of saying that string parameters should be enclosed in
double quotes, just show the quotes in the relevant commands.
Also, rename the parameters, to better fit the subsequent description.
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().
This addresses https://savannah.gnu.org/bugs/?56432.

The /etc/nanorc file should not define any syntax directly (and
preferably not include any either, to not slow startup down with
syntaxes the user is never going to use), and if the ~/.nanorc file
defines a syntax directly, there is no need to use 'extendsyntax':
the command can be added to the syntax itself -- it would be better
even: it keeps things together.
Extending a syntax will be rather rare, so the amount of memory it
takes up will be minimal. It's not worth the trouble to free this
memory -- it only takes time. Plus: we don't bother to free the
memory of a syntax that gets fully redefined either.
When an included file has just been fully parsed, 'lastcolor' is still
pointing at the last color regex that was added to the list -- no need
to refind the end of this list.
Add a temporary boolean for this, because isendwin() returns TRUE
only when curses mode has actually been started with initscr() and
then exited with endwin().
The sphere, the holder, is everything *around* the partition;
it was confusing to call this holder type 'partition'.
Also correct and improve some comments.
There is no need to save, clear, and restore the mark when counting
words, lines and characters, because partitioning and unpartitioning
the buffer does not use the mark nor affect it.
