parentheses for dynamics

[Werner LEMBERG]

[lilypond 2.2.5]

While there are parentheses for accidentals (which can be used for
note heads also), parentheses for dynamics are missing and probably
can't be faked successfully from another font.  Please add them to
lilypond's wishlist.

The code in molecule-hacking.ly for adding parentheses is, umm,
non-intuitive.  Can you provide a function, say, \parenthesize (or a
scheme equivalent) which does this?
