bug#73840: [PATCH] Improved folding for citations

Hi Arash,

OK, I did this with RefTeX (checking if it's bound and enabled).  For
bibtex.el, I just require'd it inside the internal function where it's
used.  I also implemented your correction to the docs.  Please find
attached the updated patch.  Any further feedback welcome.

Thanks, best,

Paul
