So it will fit on the screen when using a standard 80-column terminal.

Don't call the latter ones Escape sequences, because both Control
and Meta sequences can be entered using the Escape key.

When finding a misspelled word, the length of the match is simply the
length of that word, and its span in columns is simply the number of
columns that it occupies.  Compute it thus directly.

When searching for a misspelled word takes a while, and the user
stops this search with ^C, then abort the spelling-checking session.

an operating directory is not the same as restricted mode.

(In restricted mode, the file browser is not available at all.)

invalid escape sequence, and when entering a verbatim keystroke.
But leaving the cursor off during Unicode input, for extra feedback.

anyway, and it will be placed back when it's needed: in the main loop.

This prevents a segfault laid bare by r5763: when trying, at startup,
to open a directory, there really is no open buffer yet.

variable for a little optimization.

Openfile can never be NULL -- it should have been called openbuffer, and
before we start fiddling with the cursor, we will always have an open buffer.
Edittop might be NULL, but that's okay.

a misspelled word twice.  And deleting the piece of dead code that was meant
to do this.  This fixes Savannah bug #47188.

When we've reached again the same line where we started and we find an
instance there, then this can only be /before or at/ the position from
where we started, otherwise we would have found it when we commenced
searching.  And so... that little piece of dead code does absolutely
nothing -- it will never fire.

It's so nice... nano is full of Easter Eggs!  :)
