a git-bisect script to find where pystache issue #53 was fixed

test_issue_53.py

#!/usr/bin/env python
# coding: utf-8

"""
A script to use in conjunction with git-bisect to find the point
in pystache's development branch at which issue #53 was fixed:

   https://github.com/defunkt/pystache/pull/53

Because git-bisect expects the "bad" outcome to come after the "good"
outcome, we take "bad" to mean the issue has been fixed, and "good" to
mean that the issue still exists.

For the initial "good" outcome, we can take the current HEAD of master:

    7ccb55fd95f0d16cde6e46774ef80f35c3a3068f

To use git-bisect:

git checkout development
git bisect start HEAD 7ccb55fd95f0d16cde6e46774ef80f35c3a3068f
git bisect run test_issue_53.py
