func Join(args []string) (string, error)
Join joins a list of arguments into a string that can be parsed with Split. Arguments are quoted only if necessary; arguments without spaces or quotes are kept as-is. No argument may contain both single and double quotes.
func Split(s string) ([]string, error)
Split splits s into a list of fields, allowing single or double quotes around elements. There is no unescaping or other processing within quoted fields.
Keep in sync with cmd/dist/quoted.go
A Flag parses a list of string arguments encoded with Join. It is useful for flags like cmd/link's -extldflags.
