[coreutils] [PATCH] tests: set fail=0 by default

[Paul Eggert]

I found this one by tracking down a bug with the latest snapshot
on Solaris.  Still haven't got to the real bug yet, but this bug
was getting in the way.

Subject: [PATCH] tests: set fail=0 by default

* tests/init.sh (setup_): Set fail=0.  This was the intent as per
<http://lists.gnu.org/archive/html/bug-coreutils/2010-12/msg00058.html>
but the assignment in mktempd_ is ineffective, since mktempd_
is used inside `` and its assignments are in a subshell.
