Even though a number is part of a filename, it is still a number, here
representing a position in a list.

(Feel free to point to a standard that says something about MP3

Seriously, I admit that I myself always number numbered MP3's with a
leading zero, but there are occasions when I receive files that are not
numbered this way, and with the "natural sort" those files are presented
in order, the way I (a human) like them to be presented.

So, for a directory with 1500 files, the time spent sorting is:
strncmp: 84 ticks
strnatcmp: 119 ticks

If it is considered to be of major importance, the strnatcmp code can
surely be optimized to cut down the difference, so no new option would be
