2.17.4 regtests

[Phil Holmes]

On my pixels comparator, they pretty much look OK.  Lots of changes where 
accidentals are involved, which is Mike's tuning of accidental spacing, I 
reckon.  The one I don't understand is markup-special-characters.ly. I've 
attached the difference image, but the summary is that with 17.2 there's a 
visible hyphen in in-nocent, and this disappears with 17.4.
