You have a point, but if we assume people to add leading zeros
*intentionally* can't we assume those people to number their files
correctly in the first place, thus not having any need for this
"natural" sorting anyway? I'm pretty confident that there are users
careless enough to name files "3", "05", "7" and expecting them to get
sorted as "3", "05", "7". If we consider leading zeros as intentional
do we need this strnatcmp at all? If we not skip leading zeros are we
treating digits as numbers at all? I wouldn't say so.
Besides, couldn't that also create a sorting like "10", "13", "02",
"04" as 0 is a character here and thus sorted separately? Such a
sorting would be wrong if one names his files always using leading
zeros, especially if numbers are always sorted first.

in that case why do we need to add additional "brain" to the naming
the user chose?

Does "alter the sorting" require you to use digits? At least I usually
prepend character if I want something to get sorted at the top or
bottom or indexes like "a", "b" after the leading number.

Ok, that was a bad example :)

well, in that case (as both strings will evaluate to the number 1) a
strcmp would be in place to break the tie. It's a corner-case as both
numbers are identical (and 00 isn't "worth" more than "0", is it?).
Thus I don't think this is much of an issue as long as it is

I'd expect the same too, but I'm among the people that don't need
strnatcmp anyway as I properly name my files ;-)

Good point. Though if we only address the naming issue we kinda create
our own sorting, don't we?
