Thanks for raising this issue.  This is how your example above looks for
me (which I slightly changed) with 'emacs -Q':

Note the fontification of '{{foo}' which is `font-latex-verbatim-face'
and due to this line in hyperref.el:

  (add-to-list 'LaTeX-verbatim-macros-with-braces-local "hyperref")

This means that the content in the first mandatory argument is
considered verbatim and the '{' directly before 'foo' is ignored as a
brace (in terms of \begingroup) and from there things go in the wrong
direction.  It is unfortunate that \hyperref can be used like this:

  \hyperref{URL}{category}{name}{text}

or

  \hyperref[label]{text}

AUCTeX currently caters for the former syntax and ignores the latter.
Maybe we should change this?  I think the latter will be more common.

What do others think?

Best, Arash
