[PATCH] user32: Avoid buffer overflow on long texts in winproc.

[Roman Pišl]

I see, I was also thinking about that. Probably not. But is there a 
better solution? And does it harm? This is the same solution as for 
example handling WM_GETTEXTLENGTH.

Ok, the patch is linked from the bug and stay in my working copy. And I 
will eventually make it better if I get some hints.

Thanks.
