Subject: Determining commit reachability
Message-ID: <4C83FEC3.3040101@gmail.com>

Given commit C, refs (branches) R, S and T what would be the best way
to test whether 'C' is reachable from any of the heads?

Checking if `git rev-list -n1 O ^R ^S ^T` produces any output is what
i came up with; is there a better (ie faster) solution?
