[PATCH] clone: fix refspec on "--single-branch" option

[Ralf Thielow <ralf.thielow@gmail.com>]

After using "git clone" with the "--single-branch"
option, the configured refspec for this repo was
"+refs/heads/*:refs/remotes/origin/*".
After fetching changes from this repo again, it'll
receive all refs instead of the single ref which
was used in "--single-branch". Fixing the refspec
that it just contains the ref of the branch which
was cloned.
