Add support for re.Pattern to validators.matches_re() (#877) Fixes #875. This adds support for pre-compiled regular expressions to attr.validators.matches_re(). This cannot be combined with flags since the pre-compiled pattern already has those. Detailed changes: - attr.validators.matches_re() now accepts re.Pattern in addition to strings; update type annotations accordingly. - Convert percent-formatting into str.format() for an error message - Simplify (private) _MatchesReValidator helper class a bit: use the actual compiled pattern, and drop the unused .flags attribute. - Simplify control flow a bit; add pointer about fullmatch emulation. - Add tests - Tweak existing test to ensure that .fullmatch() actually works correctly by matching a pattern that also matches (but not ‘full-matches’) a shorter substring.
