If size (wParam in WM_GETTEXT message) is 2 then it only has room for 1 actual
character and the terminating null terminator so the return value should be 1.

This is regardless of how long 'infoPtr->parts[0].text' is because only 1
character can be copied into buf - the terminating null isn't counted in the
return value.

I'm sure we're reading MSDN the same way :)

Ah ok, that makes sense with a little more context. :)
