Regarding (b), are you saying that this is an issue with the complete.zip after the 2020-03 update and not in the version before that? I can't find any of those files that were changed or introduced in this update. All those I checked were last updated in the 2008-01 update - which was the complete library re-issue for CCAL licensing.
In any case, the current update process checks all new files for DOS-style line endings.
