 * 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
 * shell_quote().  If it fails, it throws a Glib::ShellError exception.  The
 * @a quoted_string need not actually contain quoted or escaped text;
 * 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.
 * Shell quoting rules are a bit strange.  Single quotes preserve the literal
 * string exactly.  Escape sequences are not allowed; not even <tt>\\'</tt> --
 * if you want a <tt>'</tt> in the quoted text, you have to do something like
 * <tt>'foo'\\''bar'</tt>.  Double quotes allow <tt>$</tt>, <tt>`</tt>,
 * <tt>"</tt>, <tt>\</tt>, and newline to be escaped with backslash.
 * Otherwise double quotes preserve things literally.
 * @param quoted_string Shell-quoted string.
 * @return An unquoted string.
 * @throw Glib::ShellError
