The new sound stuff needed some fixing up.
Guidebook.mn - list start no longer specified the longest key;
in the Postscript/PDF output, the new longer one was partially
overwritten by the text which followed and in the text output,
things didn't line up cleanly anymore.
Guidebook.tex - former last list entry which became next-to-last
was missing a necessary line break. [not tested]
both - sentence punctuation: change period to semi-colon in former
last entry that's now next-to-last; vice versa in new last entry.
