Yup, and it's also consistent with many of the other functions in
distutils.util: the general trend is to return the list of files (or
directories) that you affected/created.

One inconsistency: 'mkpath()' always returns the empty list if 'dry_run'
is true.  This is not a very big deal, IMHO.

Incidentally, I don't think you want to include directories in the
list-of-things-created.  For creation/installation, it's obvious that
directories need to be created to hold the files that are supposed to be
in them.  For uninstallation, the uninstallation code should be smart
enough to remove directories that it renders empty.  That's the approach
I took in adapting your "clean" command: after cleaning is done, it
attempts to remove the "build" directory, and doesn't care if it fails.
I think a similar approach would work for uninstallation.

Anyways, the mkpath patch is checked in now.  Thanks!

Sure, I'm paranoid... but am I paranoid ENOUGH?
