I am experimenting with a version of submodule diff (using log style)
that prints the commits brought in from merges, while excluding the
merge commits themselves. This is useful in cases where a merge commit's
summary does not fully explain the changes being merged (for example,
for longer-lived branches).
I could have gone through the effort to make this more configurable, but
before doing that level of work I wanted to get some discussion going to
understand first if this is a useful change and second how it should be
configured. For example, we could allow:
$ git diff --submodule=long-log
Or a supplementary option such as:
$ git diff --submodule=log --submodule-log-detail=(long|short)
I'm not sure what makes sense here. I welcome thoughts/discussion and
will provide follow-up patches.
