revision: separate walk and unsorted flags

The `--no-walk` flag supports two modes: either it sorts the revisions given as input input or it doesn't. This is reflected in a single `no_walk` flag, which reflects one of the three states "walk", "don't walk but without sorting" and "don't walk but with sorting". Split up the flag into two separate bits, one indicating whether we should walk or not and one indicating whether the input should be sorted or not. This will allow us to more easily introduce a new flag `--unsorted-input`, which only impacts the sorting bit.
