too wide score after upgrading 2.18.1 to 2.18.2

[Marcin Gryszkalis]

Hi
After upgrading to 2.18.2 I noticed that scores are engraved with more space,
causing different splits (and in one particular example my son was working on
- I cannot fit it on one page anymore).

You can see example:
http://stuff.fork.pl/rondo-2-18-1.pdf
http://stuff.fork.pl/rondo-2-18-2.pdf
http://stuff.fork.pl/rondo.ly

I played a bit with SpacingSpanner/base-shortest-duration and other parameters
but without luck.

Are there any known important changes between lilypond versions that would
cause such change in spacing?

best regards
