I asked myself the same question some time ago. Then, I came across
bash script (this makes it more usefull in UNIX-like OSes) which I
modified only slightly. Unfortunately, I can't recall where I got it
from to give the author due credit. It was posted somewhere, so I take
the liberty to re-post it here (with my tiny modification). Basically,
you run it from the directory where the .swp files are and it will
compare the .swp with the original file and present you a vimdiff
window if the differ. Test it before production use to get familiar
with it.
