Teach format-patch, rebase and cherry a..b format

Junio C Hamano · Junio C Hamano · commit 4282c4fbddfe · 2005-08-09T23:38:50.000-07:00
Although these commands take only begin and end, not necessarily
generic SHA1 expressions rev-parse supports, supporting a..b
notation is good for consistency.  This commit adds such without
breaking backward compatibility.
