[Rd] cut.default labels when short range

[Dan Murphy]

Hello:

I stumbled across an anomaly when running cut(4,4) in that the
rightmost level's right endpoint did not display the expansion of the
range as per ?cut.default. Modifying the last example there
cut(0:6, 3)
produces the documented behavior, as does
cut(0:6, 6)
but not
cut(0:5, 5)
However,
cut(0:5, 5, dig.lab = 4)
works.

Perhaps there is another documented point I am overlooking?

Thanks for all your great work.
Dan
