If any test script is run directly with Solaris 10 /usr/xpg4/bin/sh or
/bin/ksh, it fails spuriously with a message like:
t0000-basic.sh[31]: unset: bad argument count
This happens because those shells bail out when encountering a call to
"unset" with no arguments, and such unset call could take place in
'test-lib.sh'. Fix that issue, and add a proper comment to ensure we
don't regress in this respect.

Changes from the previous version: add a proper "Signed-off-by" line,
which I had forgotten in the previous version. Sorry for the confusion.
