Hymn settings and partcombine?

[Earnest Richards]

Below is a lilypond file that is typical of some hymn settings i'm trying (the 
core of this is from hymn.ly from the snippet repository).  Basically, the 
soprano and alto are on a stave together the tenor and bass are on seperate 
staves, corresponding to RH, LH, and pedal for organ.  It's no big deal to 
rearrange the voices in the score section to have the RH be soprano only, and 
then the LH to be the alto and tenor - in a separate file.  But.... I would 
like to be able to arrange a single file that has, for example in a four stanza 
hymn, the first and second stanzas set RH:soprano and alto, LH:tenor, PED:bass; 
the third stanza set like RH:soprano, LH:alto and tenor, PED bass; then the 
final stanza set like stanzas one and two but transposed up a half-step or a 
whole step.
(see %%%comments in the score%%%)(the basic setting works great, but crashes 
when...)
