Attached is a minor patch to allow the suppression of filenames in the
output.
I am aware it's doable with a:
md5sum diffs | cut -c-32
but I find having it integrated would be more beneficial. Indentation of
the code within the if() was not done in order to make the diffs more
legible.
If approved, I can easily produce some diffs for sha1sum as well.
cheers,

Iain.
