t6006 (rev-list-format): add tests for "%b" and "%s" for the case i18n.commitEncoding is not set
t6006 (rev-list-format): add tests for "%b" and "%s" for the case i18n.commitEncoding is not set

In de6029a (pretty: Add failing tests: --format output should honor
logOutputEncoding, 2013-06-26) 'complex-subject' test was changed.
Revert it back, because that change actually removed tests for "%b"
and "%s" with i18n.commitEncoding set.  Also, add two more tests for
mentioned above "%b" and "%s" to test encoding conversions with no
i18n.commitEncoding set.
