git fetch-pack: add --diag-url
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.
