I agree.  And the documented procedure is to call it a regression until some
developer says it's not.  So both you and I are following the correct
protocol.

Actually, I think it's the artificial \noBreak that causes the trouble.  IMO
it's better to use ragged-right and \break so that we can see the ideal
spacing that LilyPond is trying to use.  Then, if we want to show a problem
that occurs in tighter spacing, go ahead and demonstrate it (perhaps even on
a different line through the use of \noBreak).
