bug#58476: buggy version sort

[Vincent Lefevre]

A regression in version sort (used as the natural sort for "ls")
has been introduced from coreutils 8.32 to 9.1:

With coreutils 8.32 (Debian 11):

$ printf "%s\n" a a0 a1 a.b a0.b a1.b | sort -V
a
a.b
a0
a0.b
a1
a1.b

With coreutils 9.1 (Debian/unstable):

$ printf "%s\n" a a0 a1 a.b a0.b a1.b | sort -V
a
a0
a0.b
a.b
a1
a1.b

This is now completely illogical.
