I know; it is just easier to see that it is correct with the quotemeta
(and correct in the face of somebody changing the message later).

I am fine with using the shell. Though keep in mind that the two
solutions will behave differently with

  EDITOR='foo; bar'

That is, system("$editor $message") will actually invoke the shell,
whereas system(split(/ /, $editor), $message) will _just_ split on
whitespace. We should do whatever is consistent with the rest of the git
commands (off the top of my head, I don't know).
