That's not how ragged-last works. The last line is scaled according to
its "ideal" spacing, even if the line before it is stretched. I think
there was an enhancement request regarding this, but I can't find it
right now.

Why do you expect this? First of all, without ragged-last-bottom, I get
2 systems. Secondly, the solution that lilypond gives has better
vertical spacing (ie. not quite as stretched) as the one you propose, at
the cost of more stretched horizontal spacing. You can tweak the
relative importance of vertical/horizontal spacing with the
page-spacing-weight variable.

Well, yes. With ragged-last-bottom = ##f, you've asked lilypond to
stretch 5 bars of music to fill a whole a4 page. It will look bad no
matter what.
