Something configurable sounds like a good idea to me. That way, users who
don't want to don't need to adapt to a change.

So, I decided to go with adding cruft to the caption string (sigh*). I
have added 'P' flag, which will set '%?' to true if the current window is
in copy/paste mode. So, if you want to simply change the color etc. of
your caption, prepend '%?%P%{XXX}%?' to your caption and you're set ('XXX'
stands for the usual attribute/color modifier). If, on the other hand,
you want to change the caption string in copy mode, change your caption
string to '%?%PCaption for copy mode%:Your usual caption%?'

* I sigh because (1) I really didn't want to add more cruft to the
  already-too-complicated caption string, and (2) this fix doesn't help
  someone who doesn't have a caption string.

A vim-like caption could indeed be useful. It can be done by, for
example, interpreting the escape sequences differently when in copy/mode.
But I really really don't want that to happen. I think it'd be much
better to leave that kind of thing to scripts (when the support for that
gets a bit more mature).

I haven't committed the changes yet, still testing (patch attached,
should someone want to try it out). Opinions?
