The last variant will likely not start working until a recently proposed
change of mine gets in. The second variant would be fine, the first
possibly not.
Your mistake simply is that the markup macro accepts a markup, and you
feed it two arguments. You either need to create a markup-list command
(and let it create a list of two markups), or you create a single
line-markup from the two markups you have. Or use concat or other ways
of combining the two markups into one.
If you don't want to think about all those intricacies, you can just
side-step the issue of the internals, and use
#(define-markup-command (jcStack layout props jcHi jcLo) (markup? markup?)
(interpret-markup layout props
#{ \markup { \smaller $jcHi \larger $jcLo } #}
)
)
and then \markup will by itself be smart enough to create a \line-markup
around the given markup list.
