This patch adds the --rewrite-url option to 'git config'. The option takes
exactly one argument; a URL that is to be rewritten according to the longest
matching url.*.insteadOf rule in the current config. The resulting URL is
printed on stdout, and 0 is returned.
The rationale for this patch is to enable access to Git's URL rewriting
functionality from shell scripts.
The URL rewriting functionality is implemented by piggybacking on the
existing URL rewriting code in remote.c.
