Did I overlook some details? As Junio said adding a command "mark" doesn't by itself solve the difficult problems related to this project.

What's the proper way to ask for an introduction? As Michael said, you can just CC me or send me a private email. But I think the most important thing right now is first to gather as much information as you can from the previous discussions on this topic on this mainling list. Perhaps you should also gather information on how git bisect works. It will help you understand what are the difficult problems. One of the problems, for example, is that git bisect can work using a "good" commit that is not an ancestor of the "bad" commit. In this case it will checkout the merge bases between the good and the bad commit. (And by the way this is related to the bug that should also be fixed as part of this project.) Then you are welcome to come back and ask questions, or suggest solutions. > I tried asking on IRC, but had no success. Sorry but I don't use IRC.
