[PATCH v4] Do not decode url protocol.

[Pascal Obry <pascal.obry@gmail.com>]

When using the protocol git+ssh:// for example we do not want to
decode the '+' as a space. The url decoding must take place only
for the server name and parameters.

This fixes a regression introduced in 9d2e942.

Ok, so this is the fourth version of this patch. Thanks again Matthieu
for the review. I think this time I got the place for the message right :)

Anyway, I think this time we properly skip the protocol decoding when
needed.
