an invalid flag to `function` is handled wrong Specifically, an invalid flag keeps the function from being defined but does not emit an error message. Fixes #2827 2016-11-16 22:00:33 -08:00			`function: Illegal function name '-a'`
			`fish: function -a arg1 arg2 name2 ; end`
			`^`
			`function: Illegal function name '--argument-names'`
			`fish: function --argument-names arg1 arg2 name4 ; end`
			`^`
			`function: Unexpected positional argument 'abc'`
			`fish: function name5 abc --argument-names def ; end`
			`^`
