ignore special locals of test frameworks

[ronny]

pytest sues __tracebackhide__ to hide frames in tracebacks,

would be nice if that was honored

This seems fixed in 0.6.1 thanks to http://launchpad.net/bugs/1107587.

not at all

__tracebackhide__ is a local one defines inside a function

the patch is about globals magically appearing

[Florent (florent.x)]

This use case is documented there http://pytest.org/latest/example/simple.html#writing-well-integrated-assertion-helpers

The merge-proposal is on GitHub, because auto-mirroring is broken since last Saturday.
