So this is a write-once scheme; you only copy the auto-props under
limited circumstances during initial creation. Anyone wanting to alter
the autoprops later is stuck with walking the tree and making largescale
changes to the repository. It's also a narrow targeted solution where a
wider scope would solve many problems.

Would you have less objection to inherited properties if we limited it
strictly to single container inheritance? If we only permitted a file
to inherit properties from it's immediately containing directory, and
didn't deal with the [much] harder case of dealing with inheritance in
the tree, would that be acceptable? This is strictly a client-code
change (and I even think I know pretty much where in the code it would
happen, based on my keyword spelunking).
