New issue 2480 by address@hidden: hideNotes and unHideNotes should  
include also TabNoteHead
http://code.google.com/p/lilypond/issues/detail?id=2480

Enhancement request: hideNotes should hide also the numbers in TabStaff.

It was not straightforward in the past, because unHideNotes reverted the  
visibility of some objects (such as stems) that must not be displayed in  
default tablature:
http://lists.gnu.org/archive/html/lilypond-user/2010-01/msg00634.html

But now the output is correct. Marc thinks that some patches according  
stems and the placement of tablature numbers may have had the side effect  
of fixing this problem:
http://lists.gnu.org/archive/html/lilypond-user/2012-04/msg00231.html

As issue 1459 is fixed, hideNotes looks ok also in TabStaff.
I think that we should add one line to the following definitions in  
property-init.ly:

hideNotes = {
  ....
  \override TabNoteHead #'transparent = ##t
}
unHideNotes = {
  ...
  \revert TabNoteHead #'transparent
}


You can test this change by compiling the file  
Documentation/snippets/new/slides-in-tablature.ly

If we change this definition, the following LSR snippet can be removed as  
soon as LSR upgrades to 2.16:
