git-merge-cache -o does all the automerges in a single shot

Browse Source 
When you pass git-merge-cache the -o option, it tries to do all the
automatic merges and possibly return error if any of them failed, instead
of the default behaviour of failing immediately after the first failed
automatic merge.

Ported from the Cogito branch - Cogito needs this behaviour.
