This was from an intentional change to place things as close as they fit

but it should have come with padding.

I added http://code.google.com/p/lilypond/issues/detail?id=3630
A good workaround is
 \override TrillPitchGroup #'horizon-padding = #0.10

I hesitate to enter a bug report for this.
The 'concaveness' is meant to describe the pattern of note-heads where 
traditionally we prefer horizontal beams.  The rest moves in response to 
the beam, so for a beam between a single note and rest I am not surprised 
that 'concaveness'  has no effect -- the single note cannot have a concave 
pattern so 'concaveness' is not checked.

Maybe Beam.damping = +inf.0 should make the beam horizontal for a rest and 
note beamed together (it does not work currently).  
You can use
  \once\override Beam.positions = #'(0 . 0)
