HTTP_PROXY and reserved characters

[pierrevandelaar]

The value of HTTP_PROXY has as format
http://user:pass@host:80/

In the password special characters can occur, like @ and !.
According to wiki (http://en.wikipedia.org/wiki/Percent-escape)
these characters must be percent-encoded, like %40 and %21.

Cabal doesn't accept percent-encoded characters.
And cabal errs on these characters (if password is a@b, Cabal doesn't look to the right site, but probably to "b@host:80" (error message is not clear enough to be certain)

[pierrevandelaar]

Note if cabal would have used my default windows proxy settings, I would have never noticed this error ;-)

That's probably an issue with the HTTP library.

This issue needs to be solved in HTTP.
