Whether to include summaries of merged commits in newly created
merge commit messages. False by default.
+merge.verbosity::
+ Controls the amount of output shown by the recursive merge
+ strategy. Level 0 outputs nothing except a final error
+ message if conflicts were detected. Level 1 outputs only
+ conflicts, 2 outputs conflicts and file changes. Level 5 and

pack.window::
The size of the window used by gitlink:git-pack-objects[1] when no
window size is given on the command line. Defaults to 10.
