Can I do that from Perl/bash? (how?)

So the delta base algorithm doesn't work without a path. I thought we
had a quick way to find blobs of similar size. If the user can't even
give us a filename (that we can use to try and build a likely path)
then they have bigger problems than the delta ;-) -- at some point we
have to provide git-paddedcell for the remaining <ahem> users.
