[PATCH] fix texinfo warning about raising section level of @appendixsubsec

[tbsaunde+speechd]

From: Trevor Saunders <address@hidden>
To: address@hidden

 the current version of fdl.texi in gnulib uses @heading, so it would
seem to make sense to use it here too.  It might make sense to switch to
the current fdl v 1.3 at some point, but we might as well fix the
warning now.
