epriestley 969d0c3e8d Use "\z" instead of "$" to anchor validating regular expressions ... Summary: Via HackerOne. In regular expressions, "$" matches "end of input, or before terminating newline". This means that the expression `/^A$/` matches two strings: `"A"`, and `"A\n"`. When we care about this, use `\z` instead, which matches "end of input" only. This allowed registration of `"username\n"` and similar. Test Plan: - Grepped codebase for all calls to `preg_match()` / `preg_match_all()`. - Fixed the ones where this seemed like it could have an impact. - Added and executed unit tests.
