I've now checked in the possibility to specify macro arguments to be
used as a replacement in the display string with a "{<num>}" syntax.
This works only for mandatory arguments.  I've started to implement the
same for optional arguments with "[<num>]" but this would probably
require the possibility to supply an alternative string if the optional
argument is not found.  I'm not sure yet how to do that, perhaps with
something like "[<num>:<alt_string>]", if it is really necessary.

The amount of original lines in the patch borders at the limit for
requiring a copyright assignment.  I've checked it in as a tiny change,
but should you provide another patch we'd require the assignment.

Does this happen all the time or only in special files?  In case of the
latter you might want to provide a sample file for reproducing the
problem.  Before that you should check if a special setting is required
by trying to reproduce the problem in an Emacs session without your
personal settings, e.g. by starting Emacs like this:
emacs -Q -l auctex
