[AUCTeX] Parsing of \newcommand should detect when macro takes no argument

[Frank Küster]

In my document preamble, I have a couple of abbreviation macros, e.g. 

\newcommand{\dtmax}{\ensuremath{\Delta t_\mathrm{max}}}
\newcommand{\proxx}{\texorpdfstring{\chemical{Pro_{20}AA}}{Pro\_20AA}}

Due to AUCTeX's fabulous parsing ability, I can enter these macros with
C-c RET etc.  However, after that I always get \proxx{} with point
inside the braces, which doesn't make sense.  On the other hand, the
syntax for \newcommand is clear - possible arguments are indicated by
its optional argument, and a situation like

\newcommand{\myCommandWithArgs}{%
  \somecommands%
  \builtinCommandWithArgs%
}

should be fairly rare in actual LaTeX documents, although it might
occur more often in style files.  

I suggest to put point right after the closing brace for such macros; I
prefer to add one (or a couple of) pairs of braces in the rare cases when
they are needed, instead of having to move point all the time.

Alternatively, this could be made customizable - in this case, the
customization could perhaps only be activated when interactively editing
a buffer (as opposed to running commands like TeX-auto-generate in batch
mode). 

Thanks for considering,
Frank
