[PATCH 1/7] completion: teach options to submodule subcommands

[bitte.keine.werbung.einwerfen@googlemail.com]

From: Cornelius Weig <cornelius.weig@tngtech.com>

The subcommands of submodule have different long-options which command
line users need to type in. Therefore, teach bash completion to support
most subcommand options for submodule.
