I like your idea and above all tying the prompt for an optional
argument to the length of the full caption: this is indeed the reason
why one should use a short caption.

I have a couple of comments:

- the caption command is inserted also in style/longtable.el and style/psfig.el

- when you add or change a customizable option (or any interesting
feature in general),  please prove its description for the manual as
well.  In addition, an entry for doc/changes.texi is warmly
recommended.  If the option is there but users have to dig into the
code to discover it (or re-read the manual to find new feature,
instead of having a clear list of additions) it'll be useful just for
you ;-)

Bye,
Mosè
