 The existing NetBSD code is a touch ungainly to modify to handle this
 context (depending on the approach) since it uses a preprocessor
 "trick", and would be uglier with macro-wrapped conditionals. Comparing
 other implementations, I see OpenBSD simply made "cut -b -n" be handled
 as "cut -c". FreeBSD, on the other hand, uses a distinct function
 "b_n_cut" with unique logic. (Neither offer anything useful I can find
 for test suite content. It would be good to find an illustration of
 where the two approaches give varied output.)
