I checked some recent YANG modules, and the extra newline problem has been
fixed.
I am finding a different issue where trailing whitespace in the author's
YANG file on github
is removed from the YangModels repo version.  E.g.
ietf-netconf-server@2023-04-17

This should be a normal non-issue, but the new proposal requires a new
revision date
every time a meaningless space is added or removed from the file. Not sure
what problem
that is trying to solve.
