Dynamics and Lyrics don't mix

[Roman Stawski]

After some playing around, I found that the following gets rid of the
warnings. It does seem a little messy, though.

-----
\version "2.13.11"
\paper{ ragged-right = ##t }

<<
  \new Staff \new Voice = "a" \relative c'' { a b c d }
  \new Dynamics \with {
    \override VerticalAxisGroup #'staff-affinity = #DOWN
  } { s4\p s\< s\! s\mf }
  \new Lyrics \with {
    \override VerticalAxisGroup #'staff-affinity = #DOWN
  } { \lyricsto "a" \lyricmode { a b c d }}
>>

My only problem now is to increase the spacing between the dynamics and
the lyrics. Ah well, back to the VerticalAxisGroup documentation...
