Sort alternate .abc in subdir 'Compact' under the booke dir. Use that as
the graphic for A5 output, assuming it will be vertically more compact.
Use Bear Dance as an example, as it has commentary that currently
overflows an A5 landscape page.
For the moment, transposed Bookes don't transpose and so don't use Compact.
Since \newcommand takes a maximum of 9 params, move the notes, history
and closing \vfill for each tune from \showtune to the text generated
for each tune in dottes.tex.tune.
