rev(1) should reverse lines, arbitrarily-separated values (à la GNU tac(1)), or words, depending on the flags specified. These lines will be supplied from the standard input.

rev [-w] [-s separator]

This offloads functionality from #22.

Turns out it needs a different name since rev(1) is a GNU utility.

I think reverse(1) would be fine.

Arbitrary delimiter(s) (e.g. out hello world | reverse -d e -d o would print hellow odlr) or -w for whitespace sounds good to me, if that"s what you mean by the usage string.

My though was that -w is for words and -d was for arbitrary delimiters, defaulting to newlines.

That seems equivalent functionally to what I figured.
