PATCH: Fix transpose-words on 1-char word

[Marc Finet <m.dreadlock@xxxxxxxxx>]

Invoking transposewords on a 1-char word lead to previous words to be
swapped, i.e. foo and bar instead of bar and x:
        # foo bar x<transpose-words>
        # bar foo x

Commit 72bd9ee6 "24825: fix internal word-boundary widgets" rewrote
that part but changed a test:
        if (!x || zleline[x - 1] == ZWC('\n'))
            return 1;
into a test plus an assignment:
        if (!x)
            return 1;
        pos = x;
        DECPOS(pos);
        if (zleline[pos] == ZWC('\n'))
            return 1;
        x = pos;
