[PATCH v2 2/5] completion: complete 'submodule.*' config variables

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

In the Bash completion script, function
__git_complete_config_variable_name completes config variables and has
special logic to deal with config variables involving user-defined
names, like branch.<name>.* and remote.<name>.*.

This special logic is missing for submodule-related config variables.
Add the appropriate branches to the case statement, making use of the
in-tree '.gitmodules' to list relevant submodules.
