MetronomeMark tweaks

[Kieren MacMillan]

Hi all,

In LSR #444 (<http://lsr.dsi.unimi.it/LSR/Snippet?id=444>), it claims  
that the snippet is obsoleted by version 2.11.50.
However, unless I'm mistaken, we don't have direct access to the  
parts of MetronomeMark (e.g., the size of the note is too big to my  
eye, \tempo doesn't support a range of tempos like "ca. 66-72", etc.).

Am I wrong? If not, isn't this snippet *not* obsolete?

Thanks,
Kieren.
