tieDown < -- > repeatTie

[Roland Goretzki]

Hi,

\version 2.12.2

if I use \stemDown for the lower voice in one staff, the ties
automatically show up, and normaly this is fine.
In some situations, however, I want to have them showing down, too.

This is possible with \tieDown, but this doesn't have any effect to a
\repeatTie.

How can I make a \repeatTie also show down, if the stems show down?

Thanks for any hint!

Best Regards           Roland
