Your heuristics seem to assume there will only ever be a maximum of one
match, which is false. I present the following example:

    $ ls foo/

And what if there are also matches for a case-insensitive search? e.g.
searching for ‘foo/bar.DAT’ in the above example.

And what if several matches are found? e.g. searching for ‘foo/BAR.DAT’
in the above example.

It seems to me this whole thing should be hashed out on ‘python-ideas’.
