Parser for the alternate URI scheme used by SCP and Git, which look like this:

user@host:path

(Git calls these URIs "scp-style" in its documentation, but most users and developers are likely to run into them in the context of Git and I couldn't find an official name or specification, so I'm going with "GitURI".)

Note that these URIs can not be transformed into normal URIs because the path is interpreted as relative on the remote, rather than absolute (as with normal URIs).
