There was a strong suggestion to enforce easserts in WINDOW_xxx_COMBINATION_P macros (see http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00696.html), and I realize all of the reasons around it; on the other side, this requires even more changes to window management code and a lot more debugging. Given the fact that this change is quite large already, I believe that an attempt to fix all glitches and corner cases of window-related code at once may create very unexpected bugs and more ugly things than this change tries to eliminate. Therefore now I'm using a "more relaxed" design, assuming that stronger internal checking may be added step by step and used to find possible subtle bugs. Dmitry
