For the records, this is the new home:
https://github.com/openlilylib/snippets/tree/master/ly/tablature

(the file is the same as in the old one, but future updates will be
pushed to the new location.. unless Urs wants to keep the old
in sync)

I can add this to the README on github.

True. Better to avoid these (likely) errors and use manual breaks.
Minimal example reworked in the new openlilylib style:

\version "2.19.40"
\include "openlilylib"

\useLibrary Tablature
% Workaround for issue #136 at
% https://github.com/openlilylib/snippets/issues/136
#(display "")
\useModule tablature.bending

% Hack needed until issue #136 is fixed:
% https://github.com/openlilylib/openlilylib/issues/136
#(ly:message "loaded")


music = \relative c'' {
  \displayLilyMusic
  \bendOn
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
  c1( d)
}

\new StaffGroup <<
  \new Voice \music
  \new TabVoice \music
>>
% comment this line and it won't compile
\layout { \autoLineBreaksOff }
