Subject: bug#38044: 27.0.50; There should be an easier way to look at a specific vc commit
Date: Sun, 03 Nov 2019 16:17:05 +0100

Often when discussing code changes, people will send an email saying
something like "this was fixed by <id>", but Emacs doesn't have a
convenient way to display that.

For that case, Emacs should have a command that prompts for an ID
(defaulting to the ID under point), and then (unless default-directory
is already in a vc-controlled directory), prompts for the directory to
look for that ID, and then display the commit.

Stefan M also commented:

This would be a separate change, because it can also be useful to see a
commit in context.
