int_to_roman() only accepts plain "int" input, which is fine since we're going to produce '###############' for any value above 3999 anyway. However, the numeric and int8 variants of to_char() would throw an error if the given input exceeded the integer range, while the float-input variants invoked undefined-per-C-standard behavior. Fix things so that you uniformly get '###############' for out of range input. Also add test cases covering this code, plus the equally-untested EEEE, V, and PL format codes.
