No. There's no misconception here. I understood perfectly well from the
explanation in your last email.

Thanks Ken. I get that.

Thanks again... I get that as well, and I've went ahead and ran 'setfacl -b'
on a top-level directory that contains all my projects per your suggestion
from the previous email. All is well.

My question was merely based on Andrey's statement that "This is
configurable" (see above); I don't know what he meant and what "this" is,
Git or Cygwin. If by saying "This is configurable" he meant running
'setfacl -b' on the top-level directory, then I simply misunderstood his
statement; I was just misinterpreting "configurable" meaning setting "noacl"
or something like that to the file system or the environment.

Since there are usually more than one way to do something, I was just
wondering if Andrey knew of another way to handle the permission issue by
the way of some configuration setting.
