* Leverages utils/cmdline/*, instead of reinventing the wheel. * Consolidates googletest_results tests/setting for clarity. * Eliminates an unnecessary variable/comments. * Removes some duplicative TODOs/fixes TODO comment formatting. * Inlines temporary variables where possible/sensible. * Moves global variables into the anonymous global namespace. * Localizes the variable initialization near its use. * Adds more helpful comments above potentially obfuscated code. * Use list/set initialization instead of using the equivalent unrolled version with `.insert()`/`.push_back()`. * Fix indentation.
