I'm having a bit of a struggle with the spacing of systems on the final page of a 12-page score.  With
\paper { ragged-last-bottom = ##t }
the final page has three systems crowded together, followed by a sea of whitespace, then the copyright line.  But with
\paper { ragged-last-bottom = ##f }
the spacing between systems is reasonable but the final system is too close to the copyright line.

I've tried various things, including:

• changing the copyright line to \markup { \center-column { " " \vspace #10 "some text" }}
• changing \paper { system-system-spacing #'basic-distance = #29 }

<chagrin> I just discovered a keyboard shortcut for "send" </chagrin>

Adding whitespace above the copyright line has no effect at all.
A small change in system-system-spacing ( #29 to #30 ) flips from no effect to the same as ragged-last-bottom = ##f.

Before I start working blindly through all 4*8 = 32 permutations of the "vertical spacing \paper" variables, please could some kind person give me a hint?

thanks, in anticipation

Well, the inevitable happened!  After a couple of hours of experimentation, I swallowed my pride and asked the list, and then almost immediately found something that worked:
\paper {
  last-bottom-spacing =
    #'((basic-distance . 12)
       (minimum-distance .12)
       (padding . 12)
       (stretchability . 12))
}

Quite why it works is a profound mystery to me, but this code will be surrounded with comments indicating that it is to be treated as a holy relic...

Sorry to waste your time.
