Too tired to do it today anyway...

This is due to the fix for
https://sourceforge.net/p/testlilyissues/issues/660/

Not related with guile2, so I'd drop it from _this_ TODO-list.

This is the current main problem, I'd say.

Probably worth adding:

(display (make-simple-markup "xy"))

results in:

2.19.51:
(#<procedure simple-markup (layout props str)> xy)

2.19.52-guile2
(#<procedure simple-markup (a b c)> xy)
Which is technically correct but not helpful.
