Subject: completion: add new __gitcompadd helper

completion: add new __gitcompadd helper

The idea is to never touch the COMPREPLY variable directly.

This allows other completion systems (i.e. zsh) to override
__gitcompadd, and do something different instead.

Also, this allows further optimizations down the line.

There should be no functional changes.
