Hello,

The commit 80754a8 says "updated names in test-ob-shell" but it
reintroduced the file test-ob-sh.el which was renamed in the parent of
that commit.

I attach a patch which changs that and various other things related to
the renaming, namely : the customize interface, the README, and a change
in org-test (the one mentionned in <87a9et6mzz.fsf@gmail.com> I guess).
