partcombine for three parts?

[Ted Walther]

Does \partcombine yield a music expression?  I tried doing this:

\partcombine \partcombine \foo \bar \baz

The results were ugly.  Lilypond complained a lot too.

warning: ignoring too many clashing note columns

The reason I ask is that Sacred Harp music from the Denson book has
three voices together in the treble clef and only one in the bass.  I
want to keep each voice separate, but I like the type of output that
partcombine produces for two voices.  How hard would it be to extend it
to work with three?  Or four?
