That doesn't matter.  When you say to the window manager to put Eamcs in 
fullscreen, the height will be 1024 pixels (if that is what you have).  And 
there will be a remainder that is not zero.  What do you purpose Emacs does 
with this extra space?  Even if we don't have any restrictions, we can't 
display a line in this leftover space.

AFAIK, the restriction to be removed is more about scroll bar width, tool bar 
and menu bar heights and so on has to be a multiple of the character width/height.
