[PATCH v3 4/7] remote rename: rename branch.<name>.pushRemote config values too

[Bert Wesarg <bert.wesarg@xxxxxxxxxxxxxx>]

When renaming a remote with

    git remote rename X Y

Git already renames any config values from

    branch.<name>.remote = X

to

    branch.<name>.remote = Y

As branch.<name>.pushRemote also names a remote, it now also renames
these config values from

    branch.<name>.pushRemote = X

to

    branch.<name>.pushRemote = Y
