I've thought about this a lot (too much), *certain* there was a
problem...but I think I'm mistaken ;-)
Once I phrase your suggestion this way, I can't find any problem with
it:
"Given a child path and it's immediate parent path, if
parent_committed_rev <= child_working_rev <= parent_working_rev, then
child can safely inherit from parent"
However, does this gain us anything? I can't come up with one example
where this change would correctly allow inheritance where it disallows
it right now. IOW, it doesn't appear to get us out of the "update your
merge target tree before merging" situation that exists right now. And
if there is a situation where it does help, I dread trying to write the
docs describing it, we'll probably just say "update your target WC
before merging" anyway (assuming some form of mixed-rev WC restriction
ultimately stays of course, no certain thing).
Of course my brain is also wrapped in inheritance knots so maybe I'm not
seeing something obvious...anyhow if I can't come up with a
counter-example tonight I'll make the change.

Fixed that.
