Bisect limited to Merge Commits

Hey,

are there any plans to add an option to skip all non-merge commits via bisecting?

git bisect start --merges-only

Imagine a "rebase feature branch" style of development. All features are developed on separate features branch which are rebased on master and immediately merged into the upstream master. Now think about lazy programmers who miss to check the build process at each commit - leading to many unbuildable commits. The only guaranteed buildable commit is often the merge commit.

Bisecting only merge commits will reduce the amount of skip commands (think about many unbuildable commits) and reduce the number of tests.

Any comments on this idea? What about extending bisect.c:do_find_bisection()
