It should be fixed in CVS now.  Thanks for the report.

A note for developers: `font-latex-match-command-with-arguments'
currently can fontify partial matches of such commands.  That means,
suppose the macro \foo expects a mandatory argument and you only have
"\foo" in the buffer, it will get fontified.  What I'd like it to do
is to fontify it only if the mandatory argument is actually present,
that means if there is "\foo{bar}" in the buffer.  I attached a patch
to this message which shows how this could be done.  The problem with
it is that it breaks some things which rely on the function being able
to fontify partial matches.  For example \item won't get fontified
anymore.  Fixing this correctly, would require information about the
arguments a command accepts.  You know, that "[{{" thingy mentioned
before.  Once we have that, the attached patch might become
interesting again.
