[PATCH] devel: add script to run tests on a patch series.

[david at tethera.net]

From: David Bremner <bremner at debian.org>

This script is a thin wrapper around git rebase --interactive, that
allows the user to fine tune patches if they break the test suite, or
violate the coding style guidelines.

The user can always run "git rebase --continue" to ignore false positives.

I decided to use perl because inplace editing with sed is non-portable.
---

I have caught several formatting violations and at least one real bug 
using this as "last step before sending to the list".

No doubt the more talented shell-scripters / perl-hackers in the crowd
can can suggest some improvements.

+# "git rebase --continue". If all else fails, "git rebase --abort" should
+# get you back to where you started.
