That applies to the whole path including the directory components which
I don't thing we'd want in this case - but correct me if I'm wrong.

It doesn't appear to support
The only reference to the feature I could find was in the top-level
git.1 man page so maybe the syntax is different.
You can also pass --icase-pathspecs or set an environment variable.

That doesn't look too bad at all but I tend not to work in big trees
like the Linux kernel. :(icase) may be worse for a deeper path where
it adds extra directory matches. Did you run these benchmarks on a
case-sensitive or insensitive file-system?

Strictly speaking, we should use * and rely on zsh completion matching
to do the filtering instead of giving git the contents of $PREFIX
anyway but that'd really slow it.

I don't think thats necessary. Committing as per the original patch
seems good to me.
