It used to be quite tricky, but on popular request Brian Ripley has added an
example how to extract the intervals using regular expression on the bottom
of the examples for cut (note:cut in base, not cut2 in Hmisc).

If someone knows of an easier way, please correct me. How about adding this
information as attribute to the standard cut?
