I am not familiar with the warning system, but it seems plausible that one 
could add to the end of .splitext (before it returns) an optional warning 
something like

if not ext and base[0] == '.':
    warn("Before 2.6, this would have returned (%s,%s) instead of (%s,%s)" 
% (ext, base, base, ext))

where base and ext have the obvious contents.  Is this what you want?
