replay: change rev walking options

Browse source 
Let's force the rev walking options we need after calling
setup_revisions() instead of before.

This might override some user supplied rev walking command line options
though. So let's detect that and warn users by:

  a) setting the desired values, before setup_revisions(),
  b) checking after setup_revisions() whether these values differ from
     the desired values,
  c) if so throwing a warning and setting the desired values again.

We want the command to work from older commits to newer ones by default.
Also we don't want history simplification, as we want to deal with all
the commits in the affected range.
