It would be good to have tests considering that syntax propertization
affects syntax-aware functions.

How about adding these?
- verbatim environment
- equation environment
- \(\), \[\] pairs
- \emph{...}
- font specification such as \textbf{...} \mathrm{...} {\bfseries ...} 
{\ttfamily ...}

I think that `(LaTeX-mode)' should come after insertion of buffer
contents because otherwise Local Variables section isn't analysed and
would be confusing when debugging after other local variables are added.

It would be enough to use `search-forward' since we know the literal
contents.

Maybe `font-latex-faces-present-p' makes the code a bit simpler.
