[Bug-AUCTeX] previews hiding significant information

[Andreas Matthias]

It took me a long time to find out the reason for a spurious empty
page in my document. And I was really astonished to see that it was
just a \cleardoublepage. Unfortunately, just that \cleardoublepage
was covered by a preview image. Wow, what a nice effect! I was
really ROFL.

Ciao
