bug#3259: FFAP still living in the ASCII world

[jidanni]

Put your cursor on the URL in "　http://adblockplus.org/blog/  "
and hit C-x C-f. Why can't FFAP deal with it? Because FFAP is still
living in the ASCII world, and needs to be beefed up.

There are too many things a URL might be embedded in. Please make FFAP
just match http........ don't worry about what is before it. There is
nobody named Carlton Httpsford, OK? The Nilton Phartphttparts are few,
don't fear. With colons fewer.

What I'm trying to say is that day after day, I run into

文章(http://adblockplus.org/blog/) leaves a ) residue in the URL.
just don't worry about what comes before the http etc. The list is endless...
