Re: note-spacing: stretch somewhat uniformly; issue 3304 (issue 36830045)

Forgot to move one magic number in the reorganization.

The behavior of the line-breaker is strange in the presence of
zero-stretchable lines; maybe the enforcement of minimum stretchability
should go there instead.

base_space - increment));
Line-spacing depended on non-zero stretchability, so either line-spacing
needs an update, or this 0.1 needs to be preserved.

A global minimum stretchability would go here.
