Close, but if the line contains an embedded \r
it will get deleted.  (I didn't mention that
requirement in my post, so you are forgiven :-)

The semantics I want are:

    - If the string does not end with \n then
      leave it alone.

    - If the string ends with \n then remove it.

    - if the character preceding the \n is \r
      then remove that too.

I'm sure it's possible to do it with sub or gsub,
I could probably write it myself after a few tries.
I'm just kind of surprised that there is no
built-in method to handle this, as snipping off
line terminators is a pretty common thing to do.

How about a new method called "snip"?
