Ugly. Why not do that "infer the real destination b/a when existing
directory b/ was given" here, without "else if" so that we can catch
"hey, b/a exists already" with the existing code? That way you do
not have to do is_directory() twice.
For that matter, perhaps we should go back to 3/6 and move the "if
dst.buf exists error out" to after wt is validated. That would make
it stand out why having these is_directory() on the same thing twice
is ugly, I would think.
