piano pedal vertical alignment question

[Mark Polesky]

When using \sustainOn and \sustainOff to make piano pedal marks,
the "Ped." glyph and the "*" glyph (which has less height) are
drawn with the tops vertically aligned. Is there a way to align 
them at the baseline without manual overrides on each \sustainOff?
If any developers are reading, I propose that this should be the
default behavior anyway...

\version "2.11.57-1"
\relative {
  c'\sustainOn^\markup default
  c\sustainOff c2
  c4\sustainOn^\markup desired
  \once \override Staff.SustainPedal #'Y-offset = #-0.45
  c\sustainOff c2
}

Thanks,
Mark
