Sorry, I meant "the other algorithms", like ato*(3) and friends,
convert leading "+" properly.
Also, the algorithm in the GNU sort does not handle a leading "-." (as in
"-.2")... the decimal -must- be led by a zero.
Interestingly, no vendor manpage that I've seen defines the format for such
numbers, or in any way indicates they don't use ato*(3) and friends.
Thankfully, there's GNU :)
