markup for partial measures

[Henning Hraban Ramm]

Greetings again,

since I mostly typeset folk songs, I need a lot of \partial measures  
(e.g. at the end or at repeats).

I can't understand why LilyPond since 2.13.xx throws warnings that  
\partial is only allowed at the beginning of a score.

The manual says, I should use a monster like "\set  
Timing.measurePosition = #(ly:make-moment -4)" instead of a simple  
"\partial 4".
It works anyway, I didn't experience cases where it didn't, but I’d  
like to avoid those warnings.

Can someone explain why this was changed? (And I really would like to  
continue using \partial or some other simple command!)


BTW: Some songbooks use partial measures at every start and end of a  
line, if the song starts with an upbeat. E.g. with a 1/4 upbeat in a  
4/4 time, every line ends with a 3/4 partial and the next starts with  
a 1/4 partial.
Some notation programs are able to do that automatically - IIRC I saw  
it with Capella.
Is that possible with LilyPond without manually inserting \breaks and  
\partials?
