It's terrifically easy to script. Instead of:

    git show $rev -- $path

you need:

    git show ${rev}^:$path >$path.old
    git show ${rev}:$path >$path.new

which in sh/bash is (you can fancy this up some):

    rev=$(git rev-parse "$1") || exit
    path=$2

followed by the two "git show" commands. Using ${rev}^ gets
you the raw hash ID of the specified revision followed by the
caret / hat suffix, which means "parent of the given rev", so
all you need to specify to the mini-script is the same rev you'd
pass to "git show" and the path name.

(I don't need this often enough to bother with the script,
I just type in the commands.)
