There's a bit later on in mergetool that errors out if you have
provided an unknown merge program (either via the command line or
through your config). The command line and the config ways should
probably behave the same, eh? If so, the case block should be brought
up one level like so:

          case "$merge_tool" in
          kdiff3 | tkdiff | xxdiff | meld | emerge)
                     ;; # happy
          *)
                     echo >&2 "We do not know how to drive $merge_tool"
                     echo >&2 "Resetting to default..."
                     unset merge_tool
                     ;;
          esac

And then remove the 'Unknown mergetool' bit.

I think either way is fine since they both let you know that you've
entered gobbledeegook or forgot to install something, so I'll defer to
you all for the choice on which way to go.
