Ah, that's sneaky.  And elegant.  And it works.  I like it.

In the particulars, it wasn't an actual holiday but that the facility
booked for other activities on the usual date of a monthly breakfast
meeting on the 1st Saturday, but I can use PUSH/POP to do the one-off

  PUSH
  OMIT 5 Oct 2019 MSG %"Meeting room previously booked%"%
  REM Sat 1 +1 AT 07:45 \
    OMIT Sun Mon Tue Wed Thur Fri AFTER \
    MSG %"breakfast meeting%" %b %2%
  POP

It also makes it easy to provide additional OMIT clauses in the event
the facility is booked and the 1st-Saturday breakfast meeting gets
bumped again.  As Dianne points out, it only works well if it's 7 (or
fewer) days for the bumping, but that was adequate for my needs at
this time.

Thanks, all!
