yeah, sorry about that.

i did wonder about adding a "# TODO: remove when toysh is done". this
actually reminds me of the issues i have running tests on macOS: the
problem there is that the /bin tools are so anemic that many of the
tests fail just because of them. i don't currently have a better idea
than having a "known good" toybox and symlinks, and having that
directory on my path (so the command being tested is coming from the
new toybox, but i can still use toybox rather than the host for the
commands used while testing --- stat being the most obvious example).

i've not been thinking very hard about it though because macOS -- like
"switching to toysh" -- is a problem for another year...
