FWIW, we didn't use "!" for negation, because then you'd have to escape or 
quote it on the command line.  ^ does't need escaping or quoting.

Note that you only need an include or exclude list -- you never need both.  So 
if ^ is the first non-whitespace character, then it's a negative list.  If not, 
it's a positive list.
