No.  #[ #] is somewhat buggy and you can't, as a consequence, have one
test use a non-4 default duration when the next test starts with a 4.

Fixing this (in order to make the tests independent) would mean that
every test starts with a default 4.  This would affect a number of other
tests.

I decided not to bother.  Try getting the tests to agree when both just
use 32.  It is not specific to those tests: you can't do this for any
other sequence of tests as well.

Description:
Issue 2602: \unfoldRepeats and \repeat tremolo 7,14,15 produces weird
output

This just shamelessly copies the logic of make-repeat into
unfold-repeats,
on the assumption that we want to have the same rules apply for creating
and unfolding tremoli.
