[tablatures] \hideNotes in tablature

[Patrick Schmidt <p.l.schmidt@xxxxxx>]

Hi all,

when \hideNotes is used in tablature either a small vertical line or  
a dot is typeset in addition to the tab notehead. Here is a tiny  
example:

\version "2.13.44"

bug =  {
  \hideNotes
  g4\3
  \unHideNotes
  c'4\3
}

\new TabStaff  { \bug }

<<
  \new Staff { \bug }
  \new TabStaff { \bug }
>>


I didn't notice this behavior in 2.13.42, so maybe it's a regression?!

HTH,

patrick
