Benno Schulenberg f7d5a82a5d search: wipe the status bar before searching again (M-W / M-Q)
So that any message that is on the status bar after the search
will be a response to this search and not some leftover.

Benno Schulenberg ee91c51e09 syntax: perl: avoid recognizing embedded hash signs as a comment starter
Require that a comment starts at the start of a line or is preceded by
whitespace.  This prevents most hash signs used for other purposes (and
what follows them) getting colored as comments.

Benno Schulenberg 8fce33afe0 text: copy leading quote characters when automatic hard-wrapping occurs
When the user is typing a long text and --breaklonglines is in effect,
then any leading comment or quoting characters are automatically added
to each automatic new line.

This fulfills https://savannah.gnu.org/bugs/?56042.

Benno Schulenberg a578d2706c copying: do not prevent M-6 from copying emptiness into the cutbuffer
The check mistakenly prevented the user from copying a region that
ended at EOF.  Removing the check also gives the user a way to clear
the cutbuffer (with M-A M-6 or ^6 M-6, for example).

Benno Schulenberg 44d38815cc display: clear the remainder of a row only when there actually is some
Make display_string() report back (via a global variable) whether the
just converted string has room to spare within the allotted span, so
that draw_row() can avoid trying to clear the remainder when there is
nothing to clear.

This fixes https://savannah.gnu.org/bugs/?56562.

Benno Schulenberg 5cfb74650d scrolling: don't overscroll when the edit window has just one row
If the edit window consists of a single row, then the do_down() call

should then be made to scroll the screen further.

Benno Schulenberg 699cacf7a4 display: don't clear a row beforehand -- just clear the remainder
It is a waste of time to first fully clear a row when right afterward
text will be written to it (for most of the row, on average).  So...
just clear the part of the row after the written text.  Curses has the
perfect function for this: clrtoeol().

Benno Schulenberg 3422ec3419 browser: draw a bar of spaces only where needed -- for the selected item
The edit window has been fully cleared just before the list-drawing
loop has started, so there is no need to wipe anything.  Only for the
highlighting bar all its characters need to be drawn with the correct
attributes.

Benno Schulenberg f3a441043d display: where needed, use slow blanking, but elsewhere do it much faster
Where the row needs to be filled with spaces with the attributes that
were set (title bar, prompt bar, and browser highlight), use printw().
But when the row needs to be actually cleared, use the much faster
clrtoeol().

This reduces the time needed to clear a full row with 95 percent.

Benno Schulenberg e6c629951f display: use a somewhat faster method to clear a row

Benno Schulenberg 01e4f85f29 tweaks: remove a check that is no longer relevant
Since commit 7028adf2 from three days ago, also the color commands of
syntaxes that are defined in a main nanorc will get parsed during a
second pass, so it is perfectly possible to extend such syntaxes
later on in the same (or another) nanorc file.

Benno Schulenberg 6bfbb2bcd9 tweaks: remove two more unneeded assignments
'opensyntax' is relevant only during the first pass through all the
nanorc files (intros_only == TRUE) when it is checked that syntax
commands are grouped properly and not mixed with others.  And
'lastcolor' is relevant only during the second pass of a specific
syntax, because only then the color commands are actually parsed.

Benno Schulenberg d82c753ba4 rcfile: at terminating points, verify that a defined syntax is not empty
Whenever, in an rcfile, a command is encountered that is not part of a
syntax definition, a currently open syntax should be closed, but only
after checking that the syntax contains at least one color command.

This fixes https://savannah.gnu.org/bugs/?56501.
