When the current window is greater than one and another tab page exists with
only one window, loading the session causes an error. The variable tracking the
current window number in 'makeopens' is not reset for each tab page.
To reproduce (tested in 7.4.692):
vim -u NONE -i NONE -N ~/.vimrc -c 'wincmd s' -c 'wincmd v' -c 'wincmd T' -c
'normal 1gt' -c '2wincmd w' -c 'mks! ~/test.vis' -c 'qa'; vim -u NONE -i NONE
-N -S ~/test.vis
