I've been wondering the purpose of the list symbols for break-align-symbols.
It seems that I'm not able to create a tempo mark tweak which would align
things on a key-signature and if that's missing to a time-signature. If I
give #'(time-signature key-signature) the mark is always aligned to a
time-signature. If I turn them around the mark is aligned to a key-signature
when it exits. If not, it is aligned to the bar line on the left. The
program reference says: "If the grob selected by the first symbol in the
list is invisible due to break-visibility, we will align to the next grob
(and so on)." When does this invisibility occur?

Anyways, I created a scheme / tweak / whatnot that accepts a second
parameter – a list of symbols. Now I can align them as I please. :-)
