Hello,
I'm almost embarassed to post this as it's the ugly result of "trying to
learn scheme and lilypond internals all at the same time" - but at least it
seems to work. I've tried to achieve exactly what you described: _If_ the
first word is a dynamic expression, then Shevek's adjustment is applied.
