Slurs and repeats

[Tim McNamara]

I can't figure out how to end a slur across a repeat into an  
alternate ending and the documentation doesn't seem to cover this.  I  
get an error message about being unable to end the slur.  Of course  
this could always be the \endUserError bug!

The workaround I have adopted is to use \repeatTie which at least  
gives me a mark on the page that works well enough; there seems to be  
no \repeatSlur equivalent.  The page renders despite the error being  
reported.  Is there a correct way to do this that I haven't been able  
to figure out?  I didn't have luck searching the archives of the  
mailing list for a solution, unfortunately.

Thanks!
