make commit message a little more consistent and conforting
It is nicer to let the user know when a commit succeeded all the time, not only the first time. Also the commit sha1 is much more useful than the tree sha1 in this case. This patch also introduces a -q switch to supress this message as well as the summary of created/deleted files. Signed-off-by: Nicolas Pitre <> Signed-off-by: Junio C Hamano <>
