I think you misunderstood my suggestion.  I was suggesting:

1) Commands \tabNumbersOnly and \tabNumberedNoteHeads (or something similar
to that) would be defined in ly/property-init.ly.

2) The default behavior of the TabVoice would be establihed in
ly/engraver-init.ly

I don't think we want to have different contexts for different ways of
displaying tablature. In general, we want to have contexts represent
different musical entities, not different ways of displaying elements in
those entities. So we don't have a separate ShapeNoteVoice, we just have a
Voice with properties set so that the NoteHeads are shape note style.  If
you use a separate context, you can't switch from one to the other (although
with TabStaff, it's not likely that you would want to do that).

I think you can make a command that sets the stencils of all of the stuff
you don't want to #'f, which would be a better way to handle it.  But I've
copied this email to lilypond-devel, in case they don't agree with me.

In my copy of engraver-init.ly, when I look at the Voice context, I see that
the /consists Dynamic_engraver is commented out, and there is a /consists
New_dynamic_engraver line just above it.  I think you should /remove
New_dynamic_engraver, and you'll get the output you want.

Thanks,

P.S.  A couple of housekeeping things:

1) It's much easier for me to follow multiple threads if they are
interleaved, instead of having new messages posted on the top.  Maybe I'm
showing my age, but traditionally top-posting is less desirable in
discussion groups (see http://en.wikipedia.org/wiki/Posting_style).

2) LilyPond standards call for universal diffs (diff -u).   Please use that
style in the future; it makes it much easier to review patches before
applying.
