Comment(by warren.weckesser):

 An initial 0 sounds reasonable.  To maintain backwards compatibility, a
 keyword argument, say `initial`, could be added.  If `initial=None`, the
 function maintains the current behavior and returns N-1 points in the
 given axis.  Otherwise, the value of `initial` is the first value of the
 result, and N points are returned in the given axis. The typical case
 would be `initial=0`.

 Ultimately, however, it would be nice if `initial=0` was the default
 behavior, so I haven't convinced myself that this would be a good interim
 solution.
