Hey. mark-modified-lines is a pretty nice feature, but it prints the mark also when one e.g. goes up in the history and then freshly starts editing the line.
In that situation, one knows obviously that one is editing the history line and thus working on a modified version. A nice alternative could be the following: One goes up to some history element, modifies it (the first time, so no mark is printed), one goes e.g. further up and then again down to the already modified line.... and *now* (because on reaches a line that has been modified, but not just now), the mark is printed. I think this would work nicely with both revert-all-at-newline On or Off. Thanks, Chris. PS: "feature request" is obviously meant in the sense of suggestion/idea.
