[THANKS] new spacing/compression warning

[Kieren MacMillan]

Hello all,

Just wanted to thank whoever(s) made the new spacing warning read (e.g.,)

    warning: compressing over-full page by 1.9 staff-spaces
    warning: page 6 has been compressed

This is ********SO******** helpful (to me, anyways), as it gives me an exact 
idea of which pages are compressed, by how much, and whether it’s worth trying 
to fix the problem.

Thank you!!!
Kieren.
