  texidoc = "The B\\\"arenreiter edition of the Cello Suites is the
most beautifully typeset piece of music in our collection of music (we
both own one. It is also lovely on French Horn). This piece does not
include articulation, but it does follows the same beaming and
linebreaking as the printed edition. This is done in order to
benchmark the quality of the LilyPond output.

As of lilypond 1.5.42, the spacing and beam quanting is almost
identical.

There are two tweaks in this file: a line-break was forced before
measure 25, we get back the linebreaking of Baerenreiter.  The stem
direction is forced in measure 24. The last beam of that measure is up
in Baerenreiter because of context. We don't detect that yet.

Note that the Barenreiter edition contains a few engraving
mistakes. The second line begins with measure 6 (but prints 5). The |:
half way in measure 13 has been forgotten.
