Browse source 
copy() copies a single file: it fetches the source root as one content and
puts it at the destination, so addressing a directory source fails, and
there is no way to mirror a tree between file contexts.

Add a recursive mode:

- a directory source is mirrored below the destination root, into it if the
  root is an existing directory, as it if it does not exist yet
- entries are enumerated with readdir(), destination directories are
  created level by level, and every leaf is put with the requested owner,
  group, and mode
- a file source is unaffected, and the destination parent must exist, as
  before

posix copy exposes the mode as -r/--recursive; the help test reference
picks up the new option.
