[PATCH 00/12] git p4: submit conflict handling

These patches rework how git p4 deals with conflicts that arise during a "git p4 submit". These may arise due to changes that happened in p4 since the last "git p4 sync".

Luke: I especially wanted to get this out as you suggested
that you had a different way of dealing with skipped commits.

The part that needs the most attention is the interaction loop that happens when a commit failed. Currently, three options are offered:

    [s]kip this commit, but continue to apply others
    [a]pply the commit forcefully, generating .rej files
    [w]rite the commit to a patch.txt file
    and the implicit <ctrl-c> to stop

After this series, it offers two:

    [c]ontinue to apply others
    [q]uit to stop

This feels more natural to me, and I like the term "continue" rather than "skip" as it matches what rebase uses. I'd like to know what others think of the new flow.

Other observable changes are new command-line options:

Alias -v for --verbose, similar to other git commands.

The --dry-run option addresses Luke's concern in

    http://thread.gmane.org/gmane.comp.version-control.git/201004/focus=201022

when I removed an unused "self.interactive" variable that did a similar thing if you edited the code. It prints commits that would be applied to p4.

Option --prepare-p4-only is similar to --dry-run, in that it does not submit anything to p4, but it does prepare the p4 workspace, then prints long instructions about how to submit everything properly. It also serves, perhaps, as a replacement for the [a]pply option in the submit-conflict loop.

Pete Wyckoff (12):
  git p4 test: remove bash-ism of combined export/assignment
  git p4 test: use p4d -L option to suppress log messages
  git p4: gracefully fail if some commits could not be applied
  git p4: remove submit failure options [a]pply and [w]rite
  git p4: move conflict prompt into run, use [c]ontinue and [q]uit
  git p4: standardize submit cancel due to unchanged template
  git p4: test clean-up after failed submit, fix added files
  git p4: rearrange submit template construction
  git p4: revert deleted files after submit cancel
  git p4: accept -v for --verbose
  git p4: add submit --dry-run option
  git p4: add submit --prepare-p4-only option
