Yuck.  The loophole may be something we may want to close later,
though (and replaced with a proper "--tags" support).

Makes sense.

This is a tangent, but the "--[no-]tags" option in "git fetch" is
misdesigned; the default is to auto-follow tags that would annotate
objects that are being fetched, and "--no-tags" is a way to decline
the auto-following.  But "--tags" is to say that all tags must be
fetched.  There is no obvious way to say "I want the auto-following
behaviour" (e.g., to override an earlier "--no-tags" or "--tags").
