[PATCH] Ligature brackets

[Juergen Reuter]

Hi!

Attached is a patch that introduces ligature brackets (anyone knows a
better term for these beasts?).  These brackets are used in modern
notation when transcribing mensural music; they simply mark a series
of notes that, in the original notation, formed a ligature.

Example:

c d e \[ f g a g \] f e d c

This puts square edges around the notes f g a g.  This, of course,
could have been implemented simplier, namely without using a spanner.
However, for future extensions, I think a spanner fits best.  I am
planning to use this syntax to enclose ligatures in general (i.e. not
only mensural or transcribed ones).

Greetings,
Juergen
