But then, while this is a valid observation, it is not related to this
patchkit, that is just adding an extra config variable, percent_type, at
some point one can try to shorten that function signature, looking at
why it was done this way originally to see if there was any reason or if
its just something to improve by shortening the function signature.

Applying Jiri's patch,

Right

I'm going thru v2 already, so far its an uncontrovertial, trivial, so
I think you better just wait a teeny bit for this to be applied and then
get on over with followup patches, ok?
