Too  much TODOs currently
Already mentioned in chTab.ly, probably more.

Too many errors, here two examples (in the second LilyPond-default
comes out wrongly as well, but not aborting):

vl = {
  e,16 g\4 cis bes g\4 e'\2 bes e' e'\2 e' bes e'\2 g\4 bes cis g\4
}

<<
  \new Staff { \clef "G_8" \vl }
  \new TabStaff \vl
  \new TabStaff
    \with { stringTunings = #guitar-tuning }
    { \chTab { \vl } #guitar-tuning  }
>>



mI = { b4 c' d' }
mII = { g a b }

ms = <<
  \mI
  \\
  \mII
>>

<<
  \new Staff { \clef "G_8" \ms }
  \new TabStaff \ms
  \new TabStaff
    \with {
      stringTunings = #guitar-tuning
      instrumentName = "chTab"
    }
    { \chTab \ms #guitar-tuning  }
>>

This would be likely one of the TODOs.
