datevec.m: Tweaks to cset e9bfb92dab01 for performance and documentation (bug #47627) * datevec.m: Use strchr() rather than ismember() for 2.25X speedup. Change warning ID for bad date format specification to follow Octave conventions. Add BIST tests for new warning. * warning_ids.m: Document new "Octave:datevec:date-format-spec" warning.
