What?!? That's *really* strange. Is extract_url.pl double-encoding the
percent, or is some script in between doing that?

Ahh, indeed, that could cause a problem. Variables are substituted
simply, in an "as if typed" manner. Take this simple example:
# foo=bar
# echo $foo
bar
Fairly straightforward. BUT, if we use an ampersand:
# foo=bar&baz
[1] 20113
baz: command not found
[1]+ Done foo=bar
# echo $foo
#
You see, the ampersand did two things there: first, it created a
sub-shell to execute 'foo=bar' in the background, and then attempted
to execute 'baz' as if it were a command. What that shell script
*should* have done is quote the argument, like this:
url="$1"
To return to my example:
# foo="bar&baz"
# echo $foo
bar&baz

It's because of the incorrectly quoted variable assignment, which is
cutting off the URL at the ampersand.
