It is but it isn't. In the original discussion about adding seq(1)
[see tech-userlevel January 2005], I pointed out that jot(1) !=
seq(1). Yes, with work seq(1) functionality could be folded in to
jot(1) or vice versa. However, in the end there may not be much
shared among them as they approach the problem domain differently.
Also jot(1) does not have seq(1)'s equal width feature. Consensus,
at the time, by core members, if I recall correctly, was that it
was ok to add seq(1).
