Open PR associated with blame

[oriongonza]

If I blame a line I get the associated commit. Then I have to yank it and copy it into https://github.com/foo/bar/commit/abcd123 and click on the PR.

It would be nice if I could do this directly from the editor.

I also have a simiar workflow where I want to open the PR that merged a particular commit.
I used to use git when-merged but realising that GitHub has an api for finding the PR, I wrote a plugin to do that.

GitHub API docs for listing PRs associated with a commit (note that there can be more than 1)
https://docs.github.com/en/rest/commits/commits?apiVersion=2022-11-28#list-pull-requests-associated-with-a-commit

I structured it in a similar way to how rhubarb interfaces with GitHub, with the idea that I could maybe move parts of the logic to rhubarb/fugitive-gitlab and other parts to fugitive.
That would allow fugitive to control the commands/bindings and git, with the logic for obtaining the url delegated to rhubarb/fugitive-gitlab.
I'm in two minds as to whether its worth it though.

Anyway, my plugin demonstrates how this could work for both GitHub/rhubarb and GitLab/fugitive-gitlab

This is just :GBrowse with extra steps.

and click on the PR.

So this feature request boils down to saving you a click. That's not nothing; I do this operation a lot myself so I see the appeal. But I'm inclined to think it doesn't justify adding a whole top level command to Fugitive.

[shumphrey]

There is the potential for saving a few more clicks/commands if there's a command to bypass blame and go straight from current line to PR that introduced that line.
But I don't disagree adding an entirely new set of commands for this seems like overkill.

I whipped up a (local) plugin that opens the commit, PR, or issue under the cursor, but it does feel like this is something that fugitive + rhubarb should be able to provide.
