[PATCH] Export with verbatim LaTeX removes spaces

["Michaël Cadilhac" <michael@cadilhac.name>]

Hi,

When LaTeX is exported verbatim, some spaces are lost.  Try for instance:
  M-: (let ((org-html-with-latex 'verbatim)) (org-html-export-as-html)) RET
on a buffer containing "$a$ $b$".  Post-blanks were simply not added
back, see below.

Thanks!

Cheers,
Michaël
