\version statement, etc.

[Paul Scott]

I may be downloading while changes are in progress.

I just downloaded and installed 2.19.80 (what happened to 2.19.66 through
2.19.79?)

2.19.80 doesn't seem to see my version statements:

plentyr3.ly:1: warning: no \version statement found, please add

\version "2.19.80"

for future compatibility

Under 2.19.80 documentation:

Changes docs refer to 2.20 and the Notation manual still seems to be for
2.19.65.
