Wow, that was easy! Unfortunately some overrides are necessary in  
order to make the glissandi look half decent. The problem is that it  
seems to be impossible to find an optimal setting for both staffs and  
tab staffs. Without the overrides the slides are not visible in  
normal staffs (not even with a 400 % zoom-in). With these overrides  
glissandi are longer in TabStaffs than in Staffs. And because of  
these overrides this snippet would have to go in selected snippets  
rather than the body of the chapter?!

slides = {
  \override Glissando #'minimum-length = #4
  \override Glissando #'springs-and-rods = #ly:spanner::set-spacing- 
rods
  \override Glissando #'thickness = #2
  c'8\3\glissando( d'8\3)
  c'8\3\glissando d'8\3
  \hideNotes
  \grace { \stemDown g16\3\glissando } \unHideNotes
  c'4\3
  \afterGrace d'4\3\glissando { \stemDown  \hideNotes
  g16\3 }
}

\score {
        <<
        \new Staff { \clef "treble_8" \slides }
        \new TabStaff {
          \new TabVoice {
                \tabFullNotation
                \slides
          }
       }
        >>
}

Thanks,
