        A <literal>TZH</literal> template pattern can match a signed number.
-       Without the <literal>FX</literal> option, it can lead to ambiguity in
-       interpretation of the minus sign, which can also be interpreted as a separator.
+       Without the <literal>FX</literal> option, minus signs may be ambiguous,
+       and could be interpreted as a separator.
        This ambiguity is resolved as follows:  If the number of separators before
        <literal>TZH</literal> in the template string is less than the number of
        separators before the minus sign in the input string, the minus sign
