sequence(nvec) is documented to return
the concatenation of seq(nvec[i]), for
i in seq(along=nvec). This produces inconvenient
(for me) results for 0 inputs.

[1] 1 2 1 0 1 2 3
Would changing sequence(nvec) to use seq_len(nvec[i])
instead of the current 1:nvec[i] break much existing code?
On the other hand, almost no one seems to use sequence()
and it might make more sense to allow seq_len() and seq()
to accept a vector for length.out and they would return a
vector of length sum(length.out),
c(seq_len(length.out[1]), seq_len(length.out[2]), ...)
