Cover the structure and link options at >=3 levels and across directories,
asserting each option's specific effect:
links -l keeps a symlink, -L dereferences it, -k follows a
directory symlink -- all on a symlink several levels deep.
dirs -d copies the top layer (file + empty dir) without recursing.
prune-empty-dirs -m drops empty chains and chains emptied by an exclude,
keeps populated ones.
hardlinks-deep -H preserves a hard link whose names live in different
directories at depth; without -H they become separate inodes.
delete-deep --delete removes a deep extraneous file/subtree; the four
delete-timing variants agree; --max-delete caps deletions;
--existing / --ignore-existing select/skip correctly.
relative-implied -R mirrors an implied directory's mode at depth;
--no-implied-dirs does not (proto 30+).
Green on master and under --protocol=29/30 (the --no-implied-dirs sub-case is
gated to protocol >= 30, where multi-component sender paths are accepted).
