This reg-test was extended by my recent patch introducing dot-merging
functionality for the Merge_rests_engraver.
Though, the inconsistence happens at a point where the
rest/dots-merging is switched off.
I really have no clue how the extended Merge_rests_engraver could have
caused this.
Also, I would have thought at this point the output should be the same as for:

\new Staff
  <<
    \new Voice { \voiceOne   r4. r4 r8 }
    \new Voice { \voiceTwo   r4. r4. }
    \new Voice { \override Dots.color = #red \voiceThree r4. r4. }
  >>

But even the above is not consistent.

So I think Carl is right about the dot column placement algorithm.

Although, I've no clue why the dot placement was different in the
reg-test in the first place.
