The code contains

%% based on regression test `scheme-text-spanner.ly'
%% Thanks, Mike

That regression test tampered with internals of LilyPond in a manner
that broke session integrity (any changes propagated to further files
processed on the command line).  It likely still does.  The internals
changed in the mean time.

It was probably a mistake to ever include this regtest.  It just gives
people bad ideas.
