bug: commandline not visible after :tabedit in maximized window

[Václav Šmilauer]

Hello,

I use gvim 7.0 patched 1-164. When doing :tabedit in a single tab buffer, 
tabs on the top appear and the window is resized so that text area is the 
same. However, when the window cannot be grown vertically (which is the case 
for (vertically) maximized window or fullscreen), vim still keeps total 
buffer height, which makes the bottom part (command line) of the buffer 
invisible - until the window size is changed, vim is notified of the change 
and calculates buffer height properly, taking tabs into account. (It doesn't 
happen for vim running in terminal).

I am unable to provide a patch for the moment; if it is a known issue, I am 
very sorry for duplicating the report.

Regards, Vaclav
