infinite loop on frame resize

[YAMAMOTO Mitsuharu]

If Emacs is invoked as

  emacs -Q --eval "(progn (split-window) (set-frame-parameter nil 'height 1))"

then it falls into infinite loop in xdisp.c:

2682      while (total_shrink > total_removed)
2683        {
2684          for (i = 0; i < nchildren; ++i)
2685            if (new_sizes[i] > min_size)
2686              {
2687                --new_sizes[i];
2688                ++total_removed;
2689    
2690                /* Out of for, just shrink one window at the time and
2691                   check again if we have enough space.  */
2692                break;
2693              }
2694        }

where total_shrink = 40, total_removed = 37, nchildren = 2, new_sizes
= {0, 4}, min_size = 4.
