OK, that is the missing piece, thank you!

i.e. sourcing tst_env.sh at the beginning before test function setup and
tst_loader.sh at the end after test function setup). I thought we would avoid
sourcing two files in the tests, that's why I haven't tried, but that's a minor
detail. And it's better solution than having tst_exec.sh, which requires
tst_run_shell.c modification, just to do the same thing (source tst_env.sh).

Kind regards,
Petr
