I just tested 1.15.0 and it seems to run ./runtest
with /bin/sh symlinked to hush. (Did not test it with
hush build with CONFIG_NOMMU=y though...)

hush accepts, but currently (1.15.0) just ignores -x.

I only regularly test that it passes its own testsuite
while hacking on it, in order to make sure we do not regress.
Try "cd shell/hush_test; ./run-all" in the source tree.

I did not specifically test that "cd testsuite; ./runtest"
works with hush.

Anyway, hush again had a lot of fixes in the latest version,
if you plan to use it heavily, switch to 1.15.x.
