That's Dmytro's script, Graham!  My bash-fu is still at an early stage.

A problem arises when, as I suspect, the default behaviour is tagline = 
##t, even when not explicitly stated in the \header block.  IOW, the 
absence of "tagline = " doesn't mean absence of a tagline. The presence 
of the tagline means convert must include the entire page in the trimmed 
area, which defeats the purpose of the trim.

If you like, I can carry on with Dmytro's script, put it into 
\scripts\auxiliar with strip-whitespace and friends, then update the CG, 
with a note about the taglines.  Marek Klein has also reminded us about 
a script Jonathan Kulp wrote in 208, called lily2image, so I'll take 
that for a spin and see what it can do.
