It simply needs to get limited: if the string is not in the first 3k
or so, don't look further for it.
However, if a 117k file already takes seconds, this also is a sign
that the regular expressions are faulty (even searching the whole file
should not take seconds at this size). And it certainly is a bug that
the inverted character range contains $ instead of \n: $ is not
special in the expression.
