[PATCH 1/3] Add pack-refs and show-ref test cases.

[PATCH 1/3] Add pack-refs and show-ref test cases.

[Christian Couder]

Some of these test cases are from Junio.
One test case is commented out because it doesn't work right now.

[PATCH 2/3] When creating branch c/d check that branch c does not already exists.

[Christian Couder]

With packed refs, there may not be a ".git/refs/heads/c" file
when branch c exists. And currently in this case, there is no check
to prevent creation of branch c/d.

This should probably be rewritten in C and done after the ref lock
has been taken to make sure no race exists though.

This is mainly to make all test cases in "t3210-pack-refs.sh" work.

Oops, sorry this is an old mail that was in my Draft folder and should not 
have been sent...
