[Python-3000] Is it possible to avoid filenames with spaces?

[skip at pobox.com]

Given that filenames containing spaces make things a bit more challenging
for tools like find and xargs would it be possible to get rid of them in the
Python source tree?  I only see two files containing spaces at the moment:

    ./Mac/Icons/Disk Image.icns
    ./Mac/Icons/Python Folder.icns

Can they be easily renamed without creating havoc somewhere else?

Thx,
