[O] escaping of #+TEXT lines: \vspace vs \vspace*

[Eric Abrahamsen]

Hi,

In a certain org file I put this line into the export options:

#+begin_src org-mode
#+TEXT: \vspace*{0.5in}
#+end_src

The starred version is necessary, obviously, since this comes before any
text, and LaTeX will ignore a plain old \vspace{} in those cases.

This currently gets escaped as \vspace*\{0.5in\}, which keeps it from
working. I noticed that regular \vspace{} is not escaped, so I went
looking in org-latex.el, but can't begin to figure out which regexp in
which function is protecting the unstarred version, but not the starred
version.

Is this fixable?

Thanks!
Eric
