I think we can't tell for sure what's intentional and what's not. All we
have is a bunch of files, and it's not our task to infer how it has come
to it. Guessing what the intention was is an intelligence of a higher
degree than the natsort!

I'm absolutely with you, Dominik. This way the thing the algorithm does
can be captured in few words, which we accurately did in the setting
names ("Interpret numbers as ..."). Special treatment of leading zeroes,
spaces and dots is too much for a usual human being to understand.

If strnatcmp tells two strings are equal then strcmp is called which
always delivers a perfectly predictable result.

I'd opt for the latter, because it's easy to understand.
