It would be best, probably in both a Git and Hg scenario, not to show a list of the commits that were stripped. Instead, it would be nice to just say something about an Hg repo having been stripped back to HASH and a Git repo having a "Reference to branch forced to SHA1" or something along those lines. Showing the hashes of a Git repo can be a security issue for users who have accidentally pushed in a password considering you can just hack them into the URL. Also, showing each commit that was stripped just clutters up the newsfeed anyway.
