git/push: allow mirrored upstreams (thanks kvik)

It's sometimes convenient to mirror repositories
to multiple locations. For example, you may be
maintaining a git server you don't yet fully trust,
and want to push to github as well.

After this change, duplicated remotes with the same
name will all get pushed to. For example:

	[remote "origin"]
		url=hjgit://orib.dev/git9
	[remote "origin"]
		url=git+ssh://[email protected]/oridb/git9
	[remote "origin"]
		url=git+ssh://[email protected]:~ori/git9

will push to all three locations on every 'git push'
