[Bug-AUCTeX] 11.85; \smash command makes preview image blank

[Tim Toolan]

Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

When using \smash, the preview image is blank.  A simple example that 
illustrates this problem is:

\documentclass{article}
\begin{document}
This is not smashed $\tilde{F}$ and this is smashed $\smash{\tilde{F}}$.
\end{document}

Note that when previewing, the first \tilde{F} will appear correctly,
and the second one will be missing.  I am not sure what the best
solution to this is, but redefining the \smash command to do nothing
before generating the images would probably fix it.
