I suspect hard since Dscho punted on it in the original series. :) If I
understand correctly, it would require having an NTFS filesystem, and
generating 10,000+ files with a clashing prefix.

Thanks, fixed.

This is directly moved from the existing code. I'd prefer to keep the
overall structure intact to make that clear.

Yeah, I agree that's worth doing. I took (b), as "dotgitx" implies that
"x" is "modules", etc. I had originally planned to automatically turn
"gitmodules" into "is_ntfs_dotgitmodules", too, but it required
macros and string-pasting. So I decided it was a bit too ugly. :)
