Okay. > Does such a change even make sense (it's one of my first patch to git, > so I'm not really sure what your criteria in this respect are)? Welcome! As to the patch, I cannot speak for Junio, of course, but my preference would be to keep the return type. Traditionally, functions that can fail either die() or return an int; non-zero indicates an error. In this case, it seems that we do not have any condition (yet...) under which an error could occur. It does not seem very unlikely that we may eventually have such conditions, though, hence my preference.
