These can both be auto.

While reviewing this patch because of bug #133047 I've found a couple of issues, although they didn't seem to cause the regression.

> Source/WebCore/editing/TextCheckingHelper.cpp:80
> -    int wordStart = textBreakCurrent(iterator);
> -    while (0 <= wordStart) {
> +    for (int wordStart = textBreakCurrent(iterator); wordStart > 0; ) {

The while loop condition was wordStart >= 0, shouldn't the for loop one be wordStart >= 0 too?

> Source/WebCore/editing/TextCheckingHelper.cpp:258
> -        if (!(len == 1 && chars[0] == ' ')) {
> -            
> +        if (textLength == 1 && text[0] == ' ') {

This was !() before, I guess we don't want to enter the if when the text is just one space.

Yes, you are right about both.

I guess we don’t have any test coverage for either of these code paths. Ideally we’d make a regression test for this, but I think we should submit a patch right away to fix both even without a test. Would you be willing to do that, or would you like me to do it (or get someone else to do it)?

I was indeed wrong, those changes (actually the second one) fix the regression in the GTK+ port, but I forgot to enable the spell checker when I tested it :-P I'll write the patch.
