My desire is for just one in-between mode, which I want for scanning
top-level. That desired mode is to have pitch-names loaded, but without
the scanner accepting music with durations. I want to talk about it
while it is un-baked.

The difficulty in putting the lexer in the correct mode, after music
functions with variable argument lists, is related to the mailing list
discussion on "GLISS".

This is the version that allows digits at the *end* of identifiers,
which might not be wise.  See the tracker
<http://code.google.com/p/lilypond/issues/detail?id=1670>
The regression test changes demonstrate its conflict with
possibly-useful syntax; I was surprised how few changes were needed.

I have been waiting with this for over a year, so of course I will not
try to push anything forward until this "GLISS" dicussion is done.
