jove 4.9 (Q-R-S C-w is undoable too ...)

[Rob McMahon]

(I hope people don't get the impression that I don't like jove, I think it's a
fine replacement for "real" emacs (GNU emacs) where that is unusable because
of its size.  This string of articles is me tidying up the rough edges before
I let people loose on it.  It's a string of articles so that people can pick
and choose about what patches they want to take.)

In query-replace-string, C-w is undoable by C-u if you don't change more than
the single line that contained the match.  It gets it a bit wrong if you
change more than this, so you might treat this change with a bit of suspicion.
I think it's useful in spite of that.  (I've applied the patch to fix C-w not
deleting before this.)
