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".
