Reduce a special case for false positives in sf.

Browse Source 
There seem to be cases with a repeated horizontal speed increase which
should be covered by the bunnyhop mechanisms. The first increase will
not go as high as possible but have 0 y-diff, while the second one will
trigger a violation with a higher y-diff and another increas in the
horizontal distance. This commit does not cover a general multi-step
speed-increase case, but just attempts to catch this special case.
