Well, if the ACL isn't doing anything, it's just wasting a block on my
disk, and slowing down access to the file as yet another block has to
be looked at. Ya, not a big deal, but you know me, I'm persnickety.

Yes, it does, doesn't it. I have a feeling it might have something to
do with the strange "full-control" mapping samba does, and there are
tuneables for that.
Open to more ideas! I'll toy with the samba options to see if I can
get it to return to sanity.
I guess I can poke around more to see why group samba can't read with
that ACL... thought it's so bonkers that I didn't even want to go down
that rabbit hole.
Trying really hard to not do one suggestion: cron.daily find -exec
setfacl -b {} \;
Lastly, wonder why no other app besides Office does this...
