Notes are closer to the key signature but with no confusion and it
remains perfectly readable, IMHO.  After a second look the measures
are indeed quite compressed, and the space between the bar line and the
first note is very very tight in the passage I am speaking about.

I attached the output for 2.14.2 and 2.15.6.  I was not able to reduce
it to a few measures, because with such minimal example LilyPond prints
only one measure per line, even with 2.14.2.  It is only with the full
score that I get 2 measures per line by default.
I'm sure you would recognise public domain's most famous piece of music!
I am hereby speaking of measures 20 and 21.  IMHO the overall output
was better with 2.14.2, but I assume LilyPond cannot improve for every
possible score but try to give a better output in general.

Yes I know that.  But here I'd like to say "do not break after one
measure only, put at least 2 measures per line".  Something like
 min-measures-per-line = 2  (similar to a request made several times on
lilypond-user, as there is min-systems-per-page for vertical spacing).

I do not want to impose break (or "non-break"), because it would depend
on the first break.  For example, if I want to impose 2 measures per
line in a specific passage, let's say in the passage 1–4, in the fist
case:
    … | 1 |
  | 2 | 3 |
  | 4 | …
I would have \noBreak between 2 and 3 if there is (naturally) a break
after 1, but in the second case:
  | … | … |
  | 1 | 2 |
  | 3 | 4 |
  | … | … |
I should impose \noBreak between 1–2 and 3–4.
This is completely different!  So I would need also to impose where to
break at the beginning of the passage, which could lead to "non optimal"
output in the first part of the score.

Anyway, I am a bit complaining but this is of course nitpicking.

Cheers,
Xavier
