[PATCH] git completion: minor improvements

[Daniel Shahaf <d.s@daniel.shahaf.name>]

- 'git rebase': complete arguments in the same word as the option

- 'git commit': provide message for --fixup/--squash
---
Since this isn't a destabilizing change, I'll go ahead and push this
myself later this week unless I hear otherwise.

Daniel
