Sticking overlaps tuplet

[Jesse F . Engle]

Operating System -- Mac OS 10.3.9
LilyPond Version -- 2.10.9 Stable

Bug Description -- When a percussive sticking ('R' for right hand, and 'L' for
left hand) is specified for notes in a tuplet, the sticking collides with the
tuplet number and/or the tuplet bracket.

As far as I know, sticking is usually notated in the space either above or below
the staff, away from any dynamic markings or accents, and in a straight and
uniform line; it doesn't follow the contour of the note beams. Perhaps a
subclass of the Lyric_engraver could handle this?

%%% Bug Example

\paper {
        ragged-right = ##t
}

\new RhythmicStaff {
        \time 1/4
        \times 4/6 { c16^"R" c^"L" c^"R" c^"L" c^"L" r }
}
