>Description:
If you want to generate a simple integer sequence with jot, it behaves
illogical.
jot 10 1
and
jot 10 - 10
work as expected (generating 1-10), but
jot - 1 10
generates each number a few times. From reading the source && manual,
I realize this is because it forces reps=100.
This behaviour seems unlogic to me, and it certainly isn't usefull to
anybody, thus I have created a patch to force s=1 in these cases.
I also default s=-1 in case the start is bigger than the end, otherwise
you would just get an "impossible stepsize" error.
I would be happy if this could be included :)
