epriestley cc3641e633 Prevent ArcanistBundle from generating patches with overlapping hunks
Summary: We currently may generate patches which have hunks that include overlapping context. Git was okay with this until at least 1.7.3.4, but started rejecting these patches some time later.

We already attempt to detect and prevent this condition, we just don't do a very good job of it. Fix the check so that we avoid generating overlapping hunks.

Test Plan:

  - Cleanly applied troublesome patches under Git 1.7.7.2.
  - Used "arc export --git" to verify patches generate without overlapping sections.
  - Locally changed $context to 2 and 1, verified patch behavior was reasonable.

PROJECT STATUS: CAVEAT EMPTOR

This is an unstable preview release. I'm open sourcing some of Facebook's
internal tools, but they'll be unstable for at least a couple months.

WHAT IS ARCANIST?

Arcanist is the CLI for Facebook's code review tool, Differential. Since
Differential isn't released yet, it may not be terribly useful on its own.
