I don't think commonprefix should be changed, precisely because it might break apps. I also think it should not live in os.path, because it is not an abstract path operation. It's just a string operation. But it's there, so the best I can advise is not to use it.

This works. Let's accept (some variant) or Skip's desired functionality as os.path.splitprefix(); this avoid breaking existing code and uses a name that's consistent with the others. The result can be (prefix, [list of suffixes]). Trailing slashes should be handled so that os.path.join(prefix, suffix) does the "right thing".
