Comment 2 for bug 134046

Correct. If I branch a development copy from upstream's vcs, I should see the /usr/bin/env line. If I install bzr using `python setup.py install` <wink>, it would rewrite that line to /usr/bin/python in that line in the installed /usr/bin/bzr. Because Ubuntu's installation system doesn't use setuptools, packages themselves are going to have to do this rewrite so that /usr/bin/bzr ends up with /usr/bin/python in the #! line.
