To use a template for a choral song. The \layout, \book, or whatever, keeps
untouched, but sometimes there are only one, sometimes five stanza, therefore
I am only interested to type

  \include "myfinnishpreamble.ily"

  \header { 
    title = "my song"
    ...
  }

  global=...
  sopranoMusic=...
  sopranoWords=...
  altoMusic=...
  altoWords=...
  tenorMusic=...
  tenorWords=...
  bassMusic=...
  Words=...

  \include "mySATBchoral_layout.ily"
  \include "mySATBchoral_midi.ily"

Then everything would be laid out according to "mySATBchoral.ily".

But, if I have several stanza, and I want to have them between the voices,
I have to use something like

  altoWordsA=
  altoWordsB=
  altoWordsC=
  altoWordsD=

Which mixes my template, since if they are not used, I have to set them
explicitly to 

  altoWordsA={}
  altoWordsB={}
  altoWordsC={}
  altoWordsD={}

Ok, I found the solution .. I may always redefine the variables. If I place the
zero definitions to the preamble file, then I always may redefine them. I will
have definitions for very many stanza and words and, but since only non-zero
staffs are typeset (à la remove-empty-staff) the zero-definitions do not matter.

Yes, it is always inspiring to describe a problem, since the solution may be
found during explaining the problem.
