No, I don't think so. That's not what most other software does, and I
don't really think recursive behavior provides a lot of value.

We get an exec failure when trying to run it, just like if you create a
directory in place of the existing hook now. I think that's a fine
behavior.

Numbering is definitely the way I'd go on a case-insensitive file
system. Also, I don't think the ".exe" will be a problem in practice,
since generally you'd have to have a mix of binary and non-binary hooks,
which is unlikely to be super common.

I can make that change.
