I sometimes do that for as a kind of backup, when there is a chance that something disastrous could happen but that requires that I use a version control system (which is pointless for text documents with less then 2000 Words IMO) or that I remember doing that. Because once I add files to the index, i might as well create a commit and squash it later.
