I may be missing something, but I don't think such infrastructure is needed 
here — we already have most of what's needed with conditional faces.  The 
attached patch gets us 90% of the way, with the only remaining issue being 
wrapping buttons in square brackets on text terminals.

We'd also need a similar trick for check-boxes and the like.

WDYT?
