Yeah, all the reviews have been favorable here, so I think this is ready
for next.

There's still the one grammar issue pointed out in [1], but once that's
fixed I think it can be merged.

I've sent out v3 to fix up a small typo here.

That PR for gitk has been merged now. The build for git-gui still has
some issues (e.g. no askyesno helper), and fixes for this are in review
upstream [2]. I think it's fine to merge this regardless as it won't
cause builds to fail, but I'm also happy to wait for the git-gui bits to
settle first.

I think this is good to go.

This has been cooking for a while, and the latest version did address
all feedback. So maybe it's time to merge this down now.

Fine with me.

Same here, this has been cooking for a long time by now, and the
discussion around mtime has stalled after I clarified intentions and
future plans to evolve it further. So I'd love to see this merged.

Thanks!
