The reason we can't just override the text property is because it

unpure-pure-container makes sure that the chord is taken into
account in horizontal spacing calculations.  Anytime you override a
stencil, try to use an unpure-pure-container.

Where is this documented in the user manuals?  Where in the code?

You have beaten me by a few minutes :-)

unpure-pure stuff is:

http://lilypond.org/doc/v2.16/Documentation/notation/unpure_002dpure-containers

and also in the CG

http://lilypond.org/doc/v2.17/Documentation/contributor/understanding-pure-properties

The kludge I used is not documented anywhere - I looked in define-grobs.scm, saw that it was using ly:text-interface::print but that there was no callback for text, which means that it must be set in the code.  So the stencil function (or a number of other ones) could be hijacked to set text.

I'm a big fan of not calling Grob::set_property anywhere in the C++ unless it is absolutely necessary, so it'd be great to git rid of this.
