"BTW, the second issue exists without packed ref; currently we
cannot do

    git branch foo/bar
    git branch -d foo/bar
    git branch foo"

This patch also add some test cases from Linus and Junio.

This patch applies to master, that's why it doesn't contain
test cases using "git pack-refs". I will send a separate patch
for them latter.
