+ - repack.c: rename a few variables
 
- By avoiding running full two-way diff between the resulting
- revision and each of its N parents, combine-diff can be sped up
- significantly.
+ Perhaps unneeded, as the longer-term plan is to drop the codeblock
+ this change touches.
 
- Not quite sure if we want another custom tree walker for it, or it
- should be written by using existing two-way diff with the result of
- earlier intersect_path() as pathspec.

- 'more' implementation of BSD wants to be told with MORE=R

+ "log -p" output learns a new way to let users inspect a merge
+ commit by showing the differences between the automerged result

+ and the final conflict resolution that was recorded in the merge.
 
- It appears that we are coming to the consensus that trying to be
