Subject: [PATCH] git-p4: fix skipSubmitEdit regression

From: Pete Wyckoff <[email-masked]>
Date: Sat, 17 Dec 2011 12:39:03 -0500

Commit 7c766e5 (git-p4: introduce skipSubmitEdit, 2011-12-04)
made it easier to automate submission to p4, but broke the most
common case.

Add a test for when the user really does edit and save the change
template, and fix the bug that causes the test to fail.

Also add a confirmation message when submission is cancelled.

Oops.  In adding this code, I failed to test what should be the
normal code path.  How sad.

Junio:  this bug is in master.  Could you apply this fix?
