First, thanks for your review of all patchset.

I should have marked this commit as RFC. I have no problem to postpone
deleting this test fairly long time (even for 1-2 years).

But, if we really want to test basic shell commands (IMHO they should be part of
particular shell implementation code and most of these projects have it: e.g.
bash, busybox, coreutils, util-linux, ...), in this particular test it'd be more
useful to test "type" or "command" than "which", which code hasn't been changed
since 2015. Looking into openSUSE code [1], there is no patch on "which"
command.

Also, I might be a bit too aggressive when removing tests for legacy code, but
in this case Debian has deprecated "which" from it's basic tools [2], proving
there is a push to use "type" / "command -v" at least in some distros.

Kind regards,
Petr
