\tempo alignment

[Simon Bailey]

hi,

i'm probably missing something _really_ simple here, either that or  
it's not possible...

i'd like to align the \tempo mark to the clef or the time-signature  
rather than to the first note. is there an automated way to do this,  
or should i just twiddle with the extra-offset setting?

regards,
sb

p.s.: i tried \override Score.MetronomeMark #'break-align-symbol =  
#'key-signature but that doesn't work (lily doesn't complain about the  
property not being available though)
