This configuration option allows systematically rewriting fetch-only
URLs to push-capable URLs when used with push. For instance:
[url "ssh://example.org/"]
pushInsteadOf = "git://example.org/"
This will allow clones of "git://example.org/path/to/repo" to
subsequently push to "ssh://example.org/path/to/repo", without manually
configuring pushurl for that remote.
Includes documentation for the new option, bash completion updates, and
test cases (both that pushInsteadOf applies to push and that it does
*not* apply to fetch).
