Not sure if `member' is faster than `re-search-forward', but if you
replace re-search-forward with just search-forward (which requires
a bit more care since you need to manually check that matches are
anchored at bol and eol) I'm pretty sure that'll be even faster since it
will then use a more efficient search algorithm that gets faster the
longer the line of text you're looking for.
