Re: \textLengthOn - choosing which note to lengthen

[Kieren MacMillan]

Hi Carl (et al.):

Okay, this brings up a question I've had for a while…

In multi-instrument scores, I would like to avoid collisions in my  
markups (especially metronome markings) — see snippet, below. What  
I'd like to do is have Lilypond automatically stretch measures (if  
necessary) to avoid such collisions, like I've done (manually) in the  
second \score block.

Does anyone know a way of doing that? The problem with \textLengthOn  
(or equivalent things) is that the *first* measure (moment) *ONLY* is  
stretched, which results in ugly scores (parts).

Thanks,
Kieren.
