It doesn't hang for me any more, thanks. Now I only get the "normal"
test failure:

Test tramp-test33-environment-variables condition:
    (ert-test-failed
     ((should
       (string-equal
(format "%s,tramp:%s" emacs-version tramp-version)
(funcall this-shell-command-to-string "echo -n ${INSIDE_EMACS:-bla}")))
      :form
      (string-equal "28.0.50,tramp:2.5.0-pre" "-n 28.0.50,tramp:2.5.0-pre
")
      :value nil))
   FAILED  45/68  tramp-test33-environment-variables (0.198462 sec)

It looks like this "echo" command/builtin doesn't support "-n".
