revert: fix the inconsistency of status msgs in --interactive mode Before this patch we were priting every action msg before actually performing that action and that was resulting in inconsistencies; like in --interactive session if user decided to not revert any changes in a file foo, still there will be a msg on console saying "reverting foo". To fix this, I have made some changes to print status msg just before the action it is going to perform, no matter if --interactive or not. Changes made in test-revert-interactive.t reflect the changed behavior. There are also some changes in test-revert.t because of change in the order of messages.
