Speaking of the "open diff at point" feature, it's very reminiscent of 
the feature in a package of mine: 
https://github.com/dgutov/diff-hl/blob/fb9eb1cd3c4c6ed24b93de1a7cfb369d2983be74/diff-hl.el#L373-L404

And the implementation is much shorter there. So far, I don't understand 
why.

I would be happy to facilitate moving this feature to the core, but for 
obvious reasons (chiefly ease of review) I'd prefer to to be based off 
my own code. Or to see a good explanation why it's not a good choice.

If the implementation in the package above doesn't cut it for some 
reasons, similarly I'd prefer to see a patch against that code rather 
than a full reimplementation. If feasible, of course.
