Such an interpretation would cut both ways.  Think of people that use
'line-spacing' for ages or have remapped the default face font to
something higher.  They would be surprised that C-x 2 all of a sudden
complains that their window is "too small for splitting".

Also note that often the buffer to be shown in the new window, for
example via 'pop-to-buffer', is unknown to 'split-window'.

I'm not against a fix for Bug#14825.  But doing it in a clean and
consistent way will be pretty hard.  Look at how often 'split-window'
calls 'window-sizable-p'.  All these calls would have to be rewritten
in some way or the other.
