[PATCH] git fetch --tags

You can do

	git fetch --tags <linus-kernel-repo>

and it should fetch all my tags automatically.

[jc: The original by Linus fetched and overwrote branch heads with
 --all, which felt dangerous and wrong, so I removed it.  Also this
 version does not use any refs that resulted as --tags for later
 merge. ]
