Gotcha.  It looks like a bug to me too, but even after using LP for 18 
months I still don't feel qualified to label things as bugs.

Those look handy, for sure. :)

I agree with Robin that it would be cool to be able to combine the 
\stemUp and other such commands with a \once, without having to make all
