test 'modules5-8' fails on cvs-1.11.2

[Jost Martin]

Hello,

I had modules5-8 fail during make check.
This is the output in check.log:
('====' are my annotations)

------------------- snip, snip ------------------------
PASS: modules5-7
** expected:
U realmodule/a
cvs [a-z]*: Executing ../tmp/cvs-sanity/cvsroot/checkout\.sh. .realmodule..
checkout script invoked in /tmp/cvs-serv[0-9a-z]*
                           =====
args: realmodule
** got:
U realmodule/a
cvs server: Executing ''/tmp/cvs-sanity/cvsroot/checkout.sh' 'realmodule''

FAIL: modules5-8

It seems, that cvs honours (at least partly) env vars like TEMP, TMP,
TMPDIR... but the check-script is caught of guard by this.

(Maybe sanity.sh should unset those vars, right at the start (as it already 
does for 'LC...') ?)
