Felix Lange 72cbb3db6a Call FlagStringer in String() method of slice flags The default help template relies on the String() method of Flag to render the flag. For most flag types, String() indirects through FlagStringer, so that is the best place to customize flag rendering. FlagStringer was not called for slice flags because their help output differs from other flags in two ways: there can be multiple default values, and the flag name is shown two times to indicate that the flag can be specified multiple times. To make multiple values work in the FlagStringer, I simply changed GetValue() to return all values. Showing the flag more than once is achieved through a new interface, DocGenerationSliceFlag, which the FlagStringer uses to decide whether the flag is a slice flag type.		2 years ago
