Code review comment for lp:~didrocks/python-distutils-extra/update_control_file

I don't really agree with the "changing entire debian/control" expression. This code just updates only the autogenerated fields depending on project and setup.py file.
That is to say, if someone bumps the Standards-Version: 3.8.2 or XS-Python-Version:, they remain pristine.
Even if user change the fields order or adds its own fields, their're keep untouched.

That's true that keeping an history can be better for automatic merging, even for automated fields, but I really think that setup.py and debian/control may stay in sync for impacted fields.

Nevertheless, here is a new proposal with --force-control switch.
