Personally, I could not find any references to it in MSDN. I have not 
touched this function before, but it appears to me to be an internal 
WINE function, right?

The WM_GETTEXTLENGTH MSDN only says that this should be the number of 
TCHARs returned. nothing about it being an upper bound. If so, any time 
we reach this code, we potentially return the wrong value, and hence my 
suggestion for a "FIXME" there.
