Tremolo positioning

[Ralph Little]

Hi,
I saw some comments earlier on tremolo positioning.

I've seen some issues with some tremolos on semiquavers in 2.8.1 (on
windows)

\include "english.ly"

\score {
        {c'1:16
        a'1:16
        a''1:16}
}

The tremolo slashes cover the first and third note, although the "a" looks
fine.
Might be something to do with the fact that the incorrect ones are not on
the staff.

Regards,
Ralph
