histlexwords error with >! token

[Mikael Magnusson <mikachu@gmail.com>]

Even though the code appears to specially handle it, I still get this error,
 hist.c:3477: bad(1) wordsplit reading history: echo hello >! /dev/null
at: >! /dev/null
word: >|

The (1) indicates that it's the first bad that gets set, ie this one
            if (!*wptr) {
                /*
                 * End of the word before the end of the
                 * line: not good.
                 */
                bad = 1;
                loop_next = 1;
                break;
            }

and just below that is

            /*
             * Oddity 2: !'s turn into |'s.
             */
            if (*lptr == *wptr ||
                (*lptr == '!' && *wptr == '|')) {
                lptr++;
                wptr++;

I have no idea why *wptr would be NULL here. Entries that say >|
instead of >! do not produce the error.
