[PATCH 0/1] New remote groups subcommand

First submission, any guidance is appreciated.

Having recently started using remote groups I have found the feature to be missing:

  * bash completion
  * easy listing functionality
  * remote renames don't update group members with the rename (tricky)

This patch aims to fix the bash completion and simplify listing remote groups by adding a `git remote group` subcommand.

Note: the bash completion can be solved without the subcommand, using
something like:

    `git config --get-regexp 'remotes\.' | awk ...

but if this feature is intended to be supported then giving it a subcommand felt like the better approach.

Lastly, I wanted to at least add a test for the expected behavior of remote grups when a remote is renamed but found the current behavior surprising, i.e.

    $ git config --get-regexp 'remotes\.'
    file:.git/config        remotes.group1 upstream origin
    $ git remote rename origin fork
    Renaming remote references: 100% (8/8), done.
    $ git config --get-regexp 'remotes\.'
    file:.git/config        remotes.group1 upstream origin

The remote group is defined in the local config file and I would expect the rename to rename the group member here. However, should the group have been defined in the global `~/.gitconfig` the current behavior makes perfect sense.

As this was unclear, I decided not to include it in this patch series but considering that the area I am touching is the same, any comments would be appreciated. If we reach a conclusion I'm happy to create a new patch series to follow up on this.
