I'd favor, in the longer run:

 * --stat option to mean "show the diffstat between ORIG_HEAD and merge
   result" (i.e. current --summary);

 * perhaps a new configuration merge.stat to control the default for the
   above;

 * merge.log configuration to mean "add list of one-line log to the merge
   commit message" (i.e. current merge.summary);

 * perhaps a --log option to override the config default for each
   invocation.

 * deprecate --summary and merge.summary and remove them long after people
   are used to the above new set.

Transition needs to happen over time and across a major release bump.

We can do the first four in 1.5.6, and immediately declare deprecation,
and removal of --summary/merge.summary perhaps in 1.6.0.
