[PATCH] fetch: do not create ref from empty name

[Clemens Buchacher <drizzd@aon.at>]

Previously, the refspec "<src>:" would be expanded to
"<src>:refs/heads/". Instead, treat an empty <dst> just like refspecs
without a colon.

This fixes it.

Note that "git fetch origin :" is short for "git fetch origin
HEAD", which stores the remote HEAD in FETCH_HEAD. You probably want "git
fetch origin", without an explicit refspec, which defaults to "git fetch
origin 'refs/heads/*:refs/remotes/origin/*'", i.e. store remote branches in
the namespace for tracking branches.
