The regression output that changed is:

spacing-horizontal-skyline.ly "accidentals may be folded under preceding 
Two accidentals remain tucked, but this case does not:
  ceses!4...  feses! r16 

tablature-harmonic-functions.ly happens to have accidentals near ledger 
  e'''8 <dis'' gis''>8 r2.
and the extra-spacing-height prevents tucking in this case.  2.12.3 and 
2.13.46 tuck.

I also gave an extra-spacing-height to fingering, which prevented a stack 
of articulations on a middle C from tucking under the time signature. There 
were tiny shifts in a couple other tests.
