Release-critical accidentals spacing bug

[John Mandereau]

Hello,
the spacing of scores with many accidentals looks a bit strange with the
last 2.7 series. It seems that there is sometimes too much space before
accidentals, especially before sharps, and especially in sections where
there are rather widely-spaced short notes (8ths or 16ths). Since it
wasn't in 2.6, I think it is a release-critical bug.

The following snippet illustrates the problem, with PNGs attached, one
generated by 2.6.5, the other by 2.7.37. I've also noticed this problem
in examples in documentation :
