Ugh.  One name only, please.  There's already more than enough
unnecessary duplication in the Mercury standard library.

If another name is used, it should use `nl' not `newline',
since we already have `io.nl'.  Perhaps `strip_trailing_nl'?

I would be happy with the name `chomp', though.  Although it is definitely
gobbledigook to the uninitiated, it is actually quite mnemonic -- once
you've head of it once, you don't forget it (or at least it is that way
for me).
