A new commit is created automatically, joining the imported

pull::
Exactly like 'merge', but parallels 'git pull' in that
- it fetches the given commit from the specified remote
+ it fetches the given ref from the specified remote
repository.
push::
Does a 'split' (see below) using the <prefix> supplied
and then does a 'git push' to push the result to the
- repository and refspec. This can be used to push your
+ repository and ref. This can be used to push your
subtree to different branches of the remote repository.
