cryo gives the same result as on the ssh-originating host:
% ssh cryo
% bash -c '"/bin/ls /foo"' ; echo $?
bash: /bin/ls /foo: No such file or directory
127

So by reading between the lines, I assume that other
people are not seeing this kind of behavior?

That's very strange.  I haven't yet gone to the trouble of setting
up a new user account with it's own scratch ~/.ssh directory
to see if it is reproducible.

I assumed this was either a bug that nobody noticed, or it was
some kind of pilot error on my part.
