font-latex.el: Introducing new keyword class 'function-noarg'

[Arash Esbati]

Hi all,

there is a fixme in function class of
`font-latex-built-in-keyword-classes' which says:

  ;; XXX: Should macros without arguments rather be listed in a
  ;; separate category with 'noarg instead of 'command handling?

The way I see it, fixing this should be easy.  Does anybody object if I
install the patch attached (docstring and manual adjustments will
follow)?  There will be also some work in AUCTeX's style files, but that
can happen gradually.

Any comments welcome.

Best, Arash
