bug#21107: 25.0.50; ffap-next-guess does not move point for URL matches

[Greg Lucas]

Running emacs -Q, with point at the beginning of a buffer that contains
both file paths and URLs, such as:

foo
c:/Users
bar
http://www.google.com
baz


Then using `M-:' I execute:

Eval: (ffap-next-guess)

==> This returns "C:/Users" and moves point at the end of line 2.

Eval: (ffap-next-guess)

==> This returns "http://www.google.com", but leaves point at end of
line 2.

Eval: (ffap-menu)

==> This gets stuck in a loop, as seen in my Messages buffer:
