Hairpin.minimum-length gives wrong output

[Peter Toye]

This minimal criminal seems to give  wrong output. I want to make sure that the hairpin lasts for exactly one quaver (1/8 note). The first line gives a warning message that the hairpin is too short. The second line adjusts the length of the hairpin but it's now too long.

To try it out you may need to modify the number of notes depending on the paper size.

      \time 2/4
      \clef "treble"
      c''8 8 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4\break
      c''8 8 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
    }
    \new Dynamics {
      s8\sf\> s8\p s4 | s2 2 2 2 2 2 2 2 2 2 2 2
       \override Hairpin.minimum-length = #5
      s8\sf\> s8\! s4 | s2 2 2 2 2 2 2 2 2 2
    }
