what we need is like the perl lookbehind:
(?<!pattern)
A zero-width negative lookbehind assertion. For
example /(?<!bar)foo/ matches any occurrence of
"foo" that isn't following "bar". Works only
for fixed-width lookbehind.
so you could do
set alternates ="(?<!laura|madi|quin)@justpickone"
but note that I had to remove the "*" (which I think were supposed to be
".*") - since it only works for a fixed-width string...
another by the way - having a trailing .* is a nop, just eats cpu cycles
(in a patterm match)...
