A command that looks like an override must be hardwired into the parser.
I am not really all too eager to try smuggling setter functions
returning a music expression into the parser, so this is likely to stay
in that manner.  It would seem more sensible to change overrides to have
tweak syntax and forego the gratuitous equals sign.
