Hooray for this bit in particular.

Some minor changes and some questions below.

setup.py:

* Should you be trapping the existence of __init__ more generically?
  e.g. something like
        if module.endswith('__init__'):
            module = module[:-len('__init__')]

* you need spaces around the '+' on line 348

index.txt:

* when did this file get created? (Bazaar isn't good at telling me
  this for a zero length file as best I can work out.)

* are you confident deleting it is ok?

bzr.iss.cog:

* why does the new line 89 refer to "plugins\*.py" when lines 87 and 88
  use the pattern "dir\*.*"? Will this correctly move subdirectories
  within plugins?
