The parser does not match the first variant.  That's because we
currently use the following regular expression for matching:

"\\\\use\\(package\\)\\(\\[\\([^\]\\\\]*\\)\\]\\)?\
{\\(\\([^#}\\\\\\.%]\\|%[^\n\r]*[\n\r]\\)+?\\)}"

It doesn't allow backslashes inside the square brackets of the
optional usepackage arguments.  I think the original intention was to
prevent escaped square brackets from being matched.  So my proposal
would be to change this to

"\\\\use\\(package\\)\\(\\[\\(.*[^\\]\\|\\)\\]\\)?\
{\\(\\([^#}\\.%]\\|%[^\n\r]*[\n\r]\\)+?\\)}"

Question for other developers: Does that look right?  (Note that I
also removed some excess backslashes in the complemented character
alternatives.)

This is fixed in CVS.  Thanks for the report.

You are actually using XEmacs 21.4.16 with AUCTeX 11.55?  Be sure to
upgrade XEmacs as soon as possible.  XEmacs 21.4.16 was withdrawn due
to a bug which may be triggered by AUCTeX and lead to hangs and
crashes.  21.4.17 was released yesterday which contains a fix for this
bug.
