Add tests for the "usagestr" passed to parse-options.c usage_with_options_internal() through cmd_parseopt(). These test for edge cases in the existing behavior related to the "--parseopt" interface doing its own line-splitting with strbuf_getline(), and the native C interface expecting and potentially needing to handle newlines within the strings in the array it accepts. The results are probably something that wasn't anticipated, but let's make sure we stay backwards compatible with it.
