I have a project that includes a requirement line this:
-e git://git.openstack.org/openstack/neutron.git#egg=neutron
Every time update.py runs against the file, it adds an extra newline
after this. For example, if I run update.py a few times, I'll have a
few new lines in the file. This patch prevents the extra newlines
from getting added.
