slurs and \partcombine

[Ed Jackson]

Hello,

I just switched from 2.2.0 to 2.3.12 and suddenly started getting a
lot of warnings about junked slur events when parts are combined.  The
output, however, is correct.  I suspect warnings are being generated
for slurs that are being correctly removed as the parts are combined.

I searched the archives as best I could and saw that this had occurred
in some older versions, but it wasn't clear to me if it was a bug in
lilypond or in the input.  If it's the latter, I apologize for
reporting a non-bug, but would appreciate a correction to the input!

Thanks!
