python:exec can not change to the build dir correctly

[xieyanbo@…]

When output file be specified, python:exec will not change current work directory to the build dir correctly, that makes pylint report something like this: no module named xxx.

My Bitten: 0.6dev-r545

Patch attached.

I get the same error with Windows XP & Bitten: 0.6dev_r567 Python: 2.5.4 Lint runs fine from Python, but fails from Bitten: Cannot execute Python module pylint.lint: No module named pylint.lint pylint.lint doesn't exist on my working Linux system either

This seems to be a duplicate of #233 The same patch is attached to both, but it seems to have already been applied to Trunk, so can't be used to solve my issue...

As python:exec calls sh:execute internally, it sure looks highly likely that they are duplicates. I'll go for that and closing this one as a duplicate of #233.
