I did not get around to measure separate re-search-forward calls, but
total number of hits to CONSIDER (tail->bytepos, tail->charpos); during
benchmark-run is:
18 breakpoint keep y 0x000055555578be74 in buf_bytepos_to_charpos at
marker.c:353
breakpoint already hit 4,245,365 times
Combined with the fact that calling `garbage-collect' between benchmarks
makes the benchmark time nearly constant, this result may or may not
mean something.
