[patch] Limit window size on all platforms when setting lines/columns

[Daniel Harding]

Hello,

The attached patch is a follow-up to patch 7.3.117 (Problem:  When 
changing the font size, only MS-Windows limits the window size. 
Solution:  Also limit the window size on other systems. (Roland 
Puntaier)).  That patch fixed the problem that on non-MS-Windows 
systems, increasing the font size could cause the gVim window to grow 
larger than the physical screen.

A similar problem exists on non-MS-Windows systems when setting lines or 
columns.  According to the documentation for 'lines' ( or 'columns'), 
"Vim limits the number of lines [columns] to what fits on the screen." 
This is true on MS-Windows, but not true on other systems (in my case, 
Linux).  The attached patch makes the behavior consistent with the 
documentation on all systems.

Cheers,

Daniel
