I use this test when I rework setup function invocation in setup.py. So,
this test is mostly to ensure that new form of setup.py works correct.
I'd like to rework this installer-packaging patch: I have new version
with resolved todo (todo: install the txt files from bzrlib.doc.api),
with disabled doc.api tests into bzr.exe form and new one universal
helper script bzr_test_dependencies.py that check availability and
versions of third-party libraries.

I post new patch shortly.
