bug#16785: 24.3.50; Highlighting bug with ffap on a url

[Nicolas Richard]

Run this one :

emacs -Q --eval '(execute-kbd-macro (kbd "M-x f i n d - l i b r a r y <return> 
f f a p <return> C-s f f a p <return> M-x f f a p <return> <return> C-s f t p 
<return>"))'

and then type =M-x ffap=

That highlights the string ffap.el at the beginning of buffer instead of
highlighting the ftp URL (which is nevertheless suggested in the
prompt).

I had a quick look and found that the highlighting is done in
ffap-highlight, and obviously the variable ffap-string-at-point-region
is not updated when invoked on the ftp url, but I have no idea what
should be happening.
