Trill span problem

[Knute Snortum]

I have a problem with sequential trill spans.  they seems to be just a little too long and therefore they stagger vertically.  I would think the solution is to shorten the trill span but I'm not sure how to do this.

\version "2.18.2"

\relative c''' {

  \time 2/4

  | f2 \startTrillSpan \ppp

  | d2 \startTrillSpan

  | c4 \startTrillSpan d \startTrillSpan

  | c4 \startTrillSpan b \startTrillSpan

  | c2 \startTrillSpan

  | b2 \startTrillSpan

  | a2 \startTrillSpan

  | f2 \startTrillSpan

}
