The main purpose is to trace the URL parser called by git_connect() in
connect.c
The main features of the parser can be listed as this:
- parse out host and path for URLs with a scheme (git:// file:// ssh://)
- parse host names embedded by [] correctly
- extract the port number, if present
- separate URLs like "file" (which are local)
from URLs like "host:repo" which should use ssh
Add the new parameter "--diag-url" to "git fetch-pack",
which prints the value for protocol, host and path to stderr and exits.
