There's an argument for either behavior as valid. My original patch specifically documented and tested for the opposite behavior, namely that pushurl overrides any pushInsteadOf, because I intended pushInsteadOf as a fallback if you don't have an explicit pushurl set. For instance, you could use pushInsteadOf to rewrite a family of anonymous git URLs to corresponding pushable repositories, but then use an explicit pushurl to override that for a specific repository. This change would break the ability to use pushurl for its original intended purpose, namely having a local repository where fetch comes from one remote repo and push goes to another.

One use case of mine: I have a .gitconfig in my git-managed home directory which sets pushInsteadOf so that I can clone via git:// and immediately have working push. I work with a number of systems that don't have inbound access to each other but do have outbound access to the network; on some of these "satellite" boxes, I can't push changes directly to the server pushInsteadOf points to, so I can explicitly set pushurl in .git/config for that repository, which overrides the pushInsteadOf. This change would break that configuration.
