Merge Tracking Auditing - SoC

Hello all.

As many of you know, the approval for Summer of Code projects came last
week, and I've received funding to work on the auditing aspect of merge
tracking
(http://subversion.tigris.org/merge-tracking/func-spec.html#commutative-author-and-rev).
 I'm excited to get going on the project.

Over the next month, I'd like to finalize the functional spec at the
above URL. I would appreciate it if people could take a look at it and
suggest any changes. The pending questions in the spec, with varying
degrees of relevancy, are:

* How will --merge-sensitive behave for commits which remove merge info
  (e.g. reverts)?

* In the case of svn log, would the user be better served if we just
  included the original revision logs in line with the logs (i.e., no
  special indentation, etc.)?

* What about svn ls --verbose, which also shows revisions and usernames?

Thanks, and I look forward to starting the implementation.
