Hi all,
Git-blame is useful, but sometimes I want to know the series of commits that have affected a line -- not just the most recent one. Is there a way to do this?
Regards, Jez

If you use "git gui blame" or "tig blame", both have a "blame from parent commit" feature. This restarts the blame using the content as it was just before the answer you just got, so you can recursively dig. It's unfortunately a somewhat manual process.
There was a GSoC project to do what you asked, where you would indicate a set of lines and get a "git log"-like output of all the commits touching those lines. But there were some issues with the code, and it never quite made it upstream, I think. I'm not sure what the current status is. Cc'ing Thomas and Bo, who worked on it.

Hm. I guess pressing 'B' will blame the parent commit in tig. But I can't figure out how to navigate back to the old commit (before pressing 'B')? Any hints appreciated!

No, it is "," (comma) from the blame viewer in tig to blame starting from the parent of the blamed commit of the highlighted line.
Doing "B" will just re-blame starting at that commit, which will of course give you the same answer (I think it is a global "go to blame view", so it is more useful when you are _not_ in the blame viewer already).
And if you are confused at any point, "h" should give you a context-sensitive list of keystrokes.

Hm. I did look at the 'h'elp, but it wasn't mentioned there, at least not in my version (tig version 0.16-9-g7630a8f) here.

Ok. I take it back. I was blind not having it seen in the help. Searching for ',' did make me see it :-)

Pressing 'B' in the blame view reloads the blame view based on the line/commit, which is currently selected. And as Jeff points out ',' reloads based on the parent of the current commit.
Tig is very poor in terms of history (search, blame, commit) so there's is no 'back' button.

Ah. That explain I didn't find any. Thx.
