	/**

	 * quotes; if a string contains file globs, arithmetic operators,
	 * variables, backticks, redirections, or other special-to-the-shell
	 * features, the result will be different from the result a real shell
	 * would produce (the variables, backticks, etc. will be passed
	 * through literally instead of being expanded). This function is
	 * guaranteed to succeed if applied to the result of
	 * g_shell_quote(). If it fails, it returns %NULL and sets the
	 * error. The @quoted_string need not actually contain quoted or
	 * escaped text; g_shell_unquote() simply goes through the string and
	 * unquotes/unescapes anything that the shell would. Both single and
	 * double quotes are handled, as are escapes including escaped
	 * newlines. The return value must be freed with g_free(). Possible
	 * errors are in the #G_SHELL_ERROR domain.
	 *
	 * Shell quoting rules are a bit strange. Single quotes preserve the
	 * literal string exactly. escape sequences are not allowed; not even
	 * \' - if you want a ' in the quoted text, you have to do something
	 * like 'foo'\''bar'.  Double quotes allow $, `, ", \, and newline to
	 * be escaped with backslash. Otherwise double quotes preserve things
	 * literally.
	 *
	 * Params:
	 *     quotedString = shell-quoted string
	 *
	 * Returns: an unquoted string
	 *
	 * Throws: GException on failure.
