A few fixes to config path computation, esp. in tests.
Review Request #3709 — Created April 17, 2016 and submitted — Latest diff uploaded
This gets us part of the way towards making integration
tests hermetic, and unreliant on our real pants.ini.
With this commit, all unittests pass if we move our pants.ini
to a different location.
This commit also ensures that option and contrib/scrooge's
integration tests run if we move pants.ini.
It will take many followups to get all integration tests
to behave similarly.
CI passes: https://travis-ci.org/pantsbuild/pants/builds/123700526
Moved pants.ini and ran various tests.
