Partcombine workaround wanted – once more

[Simon Albrecht]

Hello,

I’ve run into what seems to be an instance of 
<https://sourceforge.net/p/testlilyissues/issues/675/>:

%%%%%%%%%%%%%%%%
\version "2.19.47"
one = {
  R1
  es'1\>
  R1\!
}
two = {
  R1
  c'1\>
  R1\!
}
\partcombine \one \two
%%%%%%%%%%%%%%%%

In these special conditions (MMR before and after, hairpins) the note 
from the second voice isn’t engraved.

I gather from the recent threads that the only workaround is using an 
extra expression for the dynamics, i.e. handling them manually?

Alas, when will a Redeemer come to make the part combiner a reliable tool?…

Best, Simon
