How do I use this?

[Jim Sabatke]

I'm having some grace not layout problems.  Setting the

#(add-grace-property 'Voice 'Stem 'thickness 1.0)

seems to work for single grace notes, but beamed grace notes 
still have really thick beams.  I've tried playing with:

beamed-minimum-free-lengths

that I found in the documentation, but have no idea of how 
to use it.  I've searched the doc's, the web and the 
lilypond wiki, with no help.

Am I trying the right thing?

Can anyone help?
