Every commentary I have read says that it was the Public CVS export
server. Apparently, it gets a copy of the BitKeeper sources, using a
utility called BitMover.

It sounds like BitMover discovered, during an update, that the file on
the export server was no longer identical to the last update copied over
from BitKeeper. This is why the detection was automatic, and not
dependent on someone noticing that the patch had been inserted.
