That file is truly remarkable, and does indeed give every indication
that it has received considerable post-Patgen attention, although it
is by no means clear that the actual /patterns/ therein were
derived empirically rather than through the use of Patgen.

My suspicion is that when a problem was noticed, the word-list was
modified and Patgen re-run, then the two "patterns" file compared
using a "differences" utility and comments added at the point(s) of
difference.  It would certainly be worth contacting those of
the original authors who are still reachable (sadly not Bernard G)
to ask what they know of this process.
