Yes, I have been reading on cut in Chapter 17 of "Learning J" -

One interesting thing: if this file had a blank line with spaces in it, it would
try to cut on space instead of CRLF.
If the last character were a regular expression indicating whitespace, then we
would have less concern about invisible gremlins b0rking the program.
