yup, I see the same nonsense for bm.cxx from gitea.

back to the drawing board, will try branch, rename, merge as described here:
https://devblogs.microsoft.com/oldnewthing/20190916-00/?p=102892/

the naming of split files looks ok or we prefer more descriptive names "event_buffer.cxx",
"transition.cxx", "message.cxx", etc?

K.O.
