[Omaha.pm] 4..1 is not 1..4 reversed

Oh... I guess this is the new thing I learned today.

This works:

$ perl -e 'print join "", 1..4'
1234

And I thought this would work too:

$ perl -e 'print join "", 4..1'

Nope. 4..1 isn't a 4 integer series. I thought it was. I guess I'll switch to "reverse 1..4". 

I thought ".." worked on any ASCII series, forward or backward. I guess it only works forward.
