So it's recursive, not iterative, but it's still essentially an
unbounded iteration... should there be some pool clearing? I guess
it's a bit tricky since each call is passing a structure to the next
one. And it's bounded by the depth of the filesystem, which hopefully
shouldn't be enormous. And you're calling from a subpool anyway. So
maybe it doesn't matter.

I don't really like the and/or in this: if I understand correctly, for
some commands --parents makes the intermediate directories, and for
some commands it adds them, right?

Our infrastructure does support per-option help descriptions: see -F
in propset, for example. Maybe have the default say "make" and
override add's to say "add"?
