I didn't know ffap was involved.  I'm content to customize 
file-name-at-point-functions, as I can't imagine when I would wan't ffap.  It 
really doesn't work well, I also got "Stack overflow in regexp matcher" a few 
times.  Hard to reproduce though.

I would expect if ffap can't produce a file that exists, or an error occurs, it 
should produce the current buffer filename.
