I asked that question myself for other submissions several times. It happens that I start to write a comment, post it and find that the submission was flagged and disappeared from the HN home page while I was writing. Sometimes they feel like absolutely innocuous submissions. I wish there is an unflag link, not the one to undo one owns flag requests (which happen due to fat fingers and tiny links.)
