Npp is creating new blank files with two spaces in name: "new  1"

I could track a possible cause of this to the newEmptyDocument() function of https://github.com/donho/notepad-plus-plus/blob/master/PowerEditor/src/ScitillaComponent/Buffer.cpp#L1089 but I'm not sure.

Maybe changing
wsprintf(nb, TEXT(" %d"), nextUntitledNewNumber());
to
wsprintf(nb, TEXT("%d"), nextUntitledNewNumber());
would fix it?
