Another reason for making an exception for boxes is the preexistence of  
\pad-to-box  as a markup command, while we now base our padding on skylines 
derived from the stencil expressions.

If we still think this way in a day, I'll repost the patch that adds the 
stencil-primitive 'with-dimensions,  supports {cresc. \pad-around 0.5 "- - -"}, 
and removes the faint box around harp-pedals.

A stencil-primitive 'with-dimension could be extended in a natural way to a 
list of boxes, if we want that in the future.
