I use 'doas make server-regress' to run tests after 'doas' my LOGNMAE
is 'root', so my GOTD_TEST_USER is also root, that's why it worked for
me, thanks for noticing.

Yeah, definitely, I've moved the check to root Makefile and it's done
now as in other tests, if I back out the change which fixes the original
crash from gotd/gotd.c, I see the following:

==== repo_req_wrong_commit ====
test_wrong_commit ok
*** Error 1 in regress/gotd (Makefile:186 'repo_req_wrong_commit': @../../gotctl/obj/gotctl -f /home/gotdev/gotd.sock stop 2>/dev/null)

Is it enough?
