I guess so. In particular, as a simple git user, I'd expect the following to work out of the box, without having to manually adjust the configuration settings:

   git clone ssh://originUrl .
   git checkout -b myBranch
   git push           # expected push to origin/myBranch, but fails
   git push origin    # expected push to origin/myBranch, but fails
   git remote add myRemote ssh://myRemoteUrl
   git push myRemote  # expected push to myRemote/myBranch - works

Will your provided patch fix these failing push commands?
