Well, oopsy daisy.  It's quite uncomplicated with regard to the grammar.
 But there is a tiny complication: as opposed to music functions et al,
markup commands have a different namespace, are supported by the markup
macro, and are not anonymous: defining a markup command does not just
define one name but a whole slew of them.

So

redBold = ...

cannot define a markup command (and never could).  I could instead
define a scheme command returning a markup.  I think that those should
work in comparable circumstances.
