That was obvious, of course. What I meant was : "whatever is this
QUOTE for?", and "will removing it break anything?".
I hazarded a guess that it might be to protect shell meta
characters, but this might be completely wrong. Just now I don't have the
time (and the nerves) to dig into vi to find out.
I will leave the QUOTE in, because we have no ksh, so it does not matter for
us.
