Those numbers were with gcc 4.4 and -Os.
With gcc 6.1 and -Os it is 67480 bytes before, and 71592 after.
With gcc 6.1 and -O2 it is 92060 bytes before, and 96172 after.

So the extra functionality costs basically four kilobytes.

That change already includes case-sensitive search, backward search,
and re-search.  Besides word-jumping and block-jumping.
