Subject: [PATCH] Don't keep the % in the URL when converted into a file name

When a file name is manufactured from a URL, the percent sign is removed to
prevent the web server or the browser from requesting a file with a % in
it.

The server or the browser would decode the percent sign if the two
subsequent bytes happened to be a valid hexadecimal byte and would request
the wrong file.
