    Add `define-event-class' and scheme spanner regtest


exposes non-local structures and is unsuitable for multiple-file
compilations.

It was introduced as
Issue 1238:[PATCH] Extra check in define-event-class
<URL:http://code.google.com/p/lilypond/issues/detail?id=1238>

(never mind the misleading issue name) with the review
<URL:http://codereview.appspot.com/1867050>.

Since it is was written with complete disregard towards bleedover, it
may be related to oscillating regtests.

I would suggest reverting it and reopening the original issue until a
solution has been designed that confines changes to a single parser
incarnation.
