Function to parse a "diff" command line to load both files into buffers and ediff them

Function to parse a "diff" command line to load both files into buffers and ediff them

[KARR, DAVID]

Quite often I find myself in a situation where I have a "diff" command that was run in a shell buffer, and I want to "transfer" that into ediff, by simply loading both of the files specified on the diff command line and then running ediff to compare them.  I could probably do this with a keyboard macro, but this just seems like something that someone must have thought of doing before.  I tried paging through the many functions that begin with "ediff-", but I didn't see anything that sounds like what I describe.  I'm using version "2.81.5".

Just wondering why you wouldn't use ediff in the first place. But if
you really want, you could write a small function that does what you
say.

Because the output originated from running "git diff" on the command line.

Yes, I could write that function.  I just didn't want to spend the time on doing something that someone else had already done, which is why I asked this.

`diff-ediff-patch` is a step in this direction, tho I don't think it
really does what you're after.

I thought of this a bit late but the magit package supports git
ediffing directly. I don't know if that meets your use case but it
seems magit does just about anything you want that has to do with git.

I'd really like this too.  I'm not a great e-lisp coder but I'd guess this wouldn't be too hard using emacs client.

Did a bit of searching and found this script that works great!
