[BUG] Password cannot contain hash

[BUG] Password cannot contain hash

[Sebastian Gniazdowski]

Hello,
if the password contains a hash, then it's impossible to clone a
repository, either with https or ssh protocols. I've had to use a
`gitg' GUI to clone such a repo.

Hmph, do you mean that

	git clone https://user:password@hosting.site/repository/
	git clone ssh://user:password@hosting.site/repository/

if the "password" has '#' in it?  Do passwords with colon, slash or
at-sign have the same issue?  Would it help to URI escape the
problematic characters?

It is a separate issue to use passwords embedded in the URLs, but
still, escaping ought to work.

It does need escaped in a URL, or we complain. I wondered if we might be
screwing it up elsewhere in the code, too, but t5550 seems to pass with
the modification below.
