Previous code was a little convoluted to follow logic
New code is shorter and logic is easier to follow
- Easier to see what happens when merge is successful
and how --no-commit affects result
- Simpler to see that for-cycle will stop when merge_was_ok is set
- Easier to spot what logic will run through best_strategy
- Easier to see that in case of ret being 2, cycle will continue
- Keep a single break case (when automerge succedes and a revision will
be created)
- Put together closing actions when automerge succedes if a revision
will be created
