[PATCHv2] git-p4: Handle p4 submit failure

From: Luke Diamand <hidden>
Date: 2016-06-15 23:07:18

This is a small reroll of Etienne's earlier patch to clean up
the p4 repo on submit failure.

The only difference is to fix the t9807- test. This test
was trying to remove a file which had already been cleaned
up as a result of this change.

  git-p4: clean up after p4 submit failure

[PATCHv2] git-p4: clean up after p4 submit failure

From: Luke Diamand <hidden>

From: GIRARD Etienne <redacted>

When "p4 submit" command fails in P4Submit.applyCommit, the
workspace is left with the changes.  We already have code to revert
the changes to the workspace when the user decides to cancel
submission by aborting the editor that edits the change description,
and we should treat the "p4 submit" failure the same way.

Clean the workspace if p4_write_pipe raised SystemExit, so that the
user don't have to do it themselves.

Thanks, I think this should be ready for 'next', then.
