description:
Delete the old style (no longer used) DEBUG mode TRACE compat macro
definitions (just to avoid any temptation to ever use them again).

Update a comment which would make no sense without following the
preceding comment which is being deleted with the macros it describes.

While here, remove another comment that referred to events that have
long past as if they were still to come.   Also a grammatical comment
correction - paragraphs start with capital letters...

NFC (even with DEBUG defined).
