As I mentioned in another message, I now agree that this should only be
reported as an error when a + expansion is attempted either from within
"skunkworks", or referring to "skunkworks". The svn cp or propset that
got us there should not cause an error, though it might be useful to
have it warn.

I think they might. It would also allow that cache to include the extra
info needed for this feature, ie: from which ancestor is the property
inherited. Additionally, it would allow easy implementation of erroring
out on "svn propdel/propedit" of an inherited property.
I think it would be a very good idea for any thinking/work on inherited
properties to happen in, or on an experimental branch off of, the
propcaching branch, to avoid undoing any of the excellent work being
