[PATCh] jit-trackdown

[David Greaves <david@dgreaves.com>]

Hi Junio

Excellent tool :)
Should really be cg-trackdown

David


This patch allows the use of symbolic commits from Cogito's
.git/refs/heads and tags structure eg:
  jit-trackdown HEAD etc/db/schema.sql
or
  jit-trackdown v3.2 etc/db/schema.sql
