* When copying a directory, if the destination exists and is not a
directory, we would previously emit an error message and exit. The

continue without descending further into the source directory.
* When copying a directory, if the destination does not exist and we
fail to create it, we would previously emit an error message and
exit. The correct behavior according to POSIX is to emit an error
message and continue. Whether to descend further into the source

seems to me to be the safer and less surprising option, so let's not
either.
