[PATCH] Protect starred commands in LaTeX export correctly

[Lawrence Mitchell <wence@gmx.li>]

* lisp/org-latex.el (org-export-latex-preprocess): Correctly
match starred command names.

Many LaTeX commands exist in both normal and starred forms.  Adjust
the regexp in `org-export-latex-preprocess' to match the starred form
as well.

Indeed it probably should, here's a patch that does exactly that,
avoiding the need for the above workaround.  With this change
\vspace*{1cm} is correctly exported like \vspace{1cm}.
