Subject: sh: Test that . /dev/null returns exit status 0 and does not preserve $?.

sh: Test that . /dev/null returns exit status 0 and does not preserve $?.

Preserving $? may cause problems particularly if set -e is in effect.

It may be useful to preserve the old value of $? in the dot script but this
must not be implemented in such a way that it would break this test.
