That sounds solvable to me -- IF the regular expression passed to
unalternates is literally identical (strcmp == 0) to a regular
expression already "alternated", then delete that expression.
Otherwise, add the expression to the "un"-list.
(I think we are doing something similar with header weeding already,
so this would just be consistent.)
