Public bug reported:
I can use seq(1) to generate sequences of large numbers if I use the
default increment:
$ seq 170141183460469231731687303715884105721
170141183460469231731687303715884105725
170141183460469231731687303715884105721
170141183460469231731687303715884105722
170141183460469231731687303715884105723
170141183460469231731687303715884105724
170141183460469231731687303715884105725
$
However, if I use an increment of 2 (which should stop 2 short of the max int,)
it starts with the max integer+1 (2^127) and outputs it forever:
$ seq 170141183460469231731687303715884105721 2
170141183460469231731687303715884105725 | less
