Thanks for your response and the hint.  I see that @ is missing in
`thing-at-point-file-name-chars', I hope that nobody names a file
"address@hidden" (corner case as you said), but I think we are on the safe
side if we match everything and reduce the support factor in future ;-)

@Tassilo: Can please apply this patch to Emacs master?  TIA.
