I do find it easier to read, though I find this even better:

bzrtools 1.1.0
     Various useful plugins for working with bzr.
     C:\work\Bazaar\plugins-repo\bzrtools

launchpad
     Launchpad.net integration plugin for Bazaar.
     C:\work\Bazaar\mydev.packs\plugins.output\bzrlib\plugins\launchpad

multiparent
     Implementation of multiparent diffs for versionedfile-like storage
 
C:\work\Bazaar\mydev.packs\plugins.output\bzrlib\plugins\multiparent.py

win32symlinks 0.92.0
     Fake symlinks support for win32 (NOTE: slow on FAT32!)
     C:\work\Bazaar\plugins-repo\win32symlinks


The only problem with automatically changing ".py[co]" => ".py" is that 
there may not *be* a .py. One could certainly ship your plugins as 
precompiled .pyo modules with all the docstrings, etc stripped out. So 
if we do it, we probably should use "os.path.isfile()" to make sure it 
really is present.

Also, I'm not sure how it would work if the .pyc file was in a .zip archive.
