I'm not sure that it will be feasible to add convert-ly rules, since
you have to deal with correctly nesting { }

I'm not sure if it's feasible, but one thing that I did have in mind
is to convert

     { c b \bold { d e } f g }

to

     { c b \bold  d \bold e f g }

ie. flattening a (markup_head_1_list + markup_list) that is inside a
markup_list. I think that you will need some more rules, but can you
try if you can make it work? Then, we won't have to introduce
additional artificial line-markup commands.

Other than that, my compliments - this looks just way cool!
