[PATCH] Tablature in LilyPond

[Lamy Jean-Baptiste]

Hi,

Here is the new version of the tablature patch for Lilypond (1.5.55) !

The input/test/tablature.ly file is an exemple.

I've tried this but it doesn't work :-(
I guess i'm not good enough at using context with Lilypond...
Can someone help me ?

OK, i now use it (in Scheme) !
BTW i've fixed a bug in pitch-semitons; this Guile function was returning
the note number and not the semitons !

Done !
The new stem property is called "avoid-note-head".

The string-tuning is now the string-tunings properties of the TabNoteHead
grob.
I prefer to keep the tab string number in the TabNoteHead grob, since it
may be usefull for other things (e.g. hacking the grob molecule brewer, so
it write letters instead numbers; if i remember well there are a few
instruments that use letters).
