They're all about unification, but I split it for bisectability, as ingo 
many times requested (and it happened for me to agree completely with it
after a while ;-)).

So, exactly because not using size specifiers can introduce bugs here, I 
did it in a separate patch. But it all end at unification in the end.

Sorry if the intention was not explicit enough.
