For example you cannot add "startup:" in the first (cond ((...)))
because "startup:" is not a "backend specific content." And some

OK, I understand. I should have spent some more time trying to
understand the code.

I'd welcome a patch for removing more flyspell overlays, but it
has to be rewritten. I'm not using flyspell so someone else will
have to do roll his sleeves.

I'd be willing to put in the effort to make a proper patch, but I need some
help to understand what is going on in this function. It is not obvious to
me.

The places flyspell-overlays needs to be removed are in the startup,
options, latex_header. Some of structures that might be used in latex like
lstlisting and verbatim where the text also should not have flyspell-overlays.

There are also some other places like label, caption and attr.
