This is only tangentially related but one of the guys at work found .rej
files obscure. He put together rej2diff, included below.

#!/bin/sh
# Vince Ho <vince@fst.net>
# Convert patch .rej rejects to proper diff format

# Convert to unified diffs by default
difftype="unified"

echo_diffhdr()
{
        local name="$1"

        # set the right context diff header stuff 
        prefix1="***"
        prefix2="---"
        [ -z "$name" ] && name="/dev/stdin"

        echo "$prefix1 $name"
        echo "$prefix2 $name-NEW"
}

# process options
while [ $# -gt 0 ]; do
        case $1 in
                -u|--unified)
                        difftype="unified"
                        shift
                        ;;
                -c|--context)
                        difftype="context"
                        shift
                        ;;
                *)
                        break
                        ;;
        esac
done

# If no arguments, run in filter mode
if [ $# -eq 0 ]; then
        (echo_diffhdr && cat) | filterdiff --format="$difftype"
else
        # Process each file
        while [ $# -gt 0 ]; do
                (echo_diffhdr ${1%.rej}; cat $1) | filterdiff --format="$difftyp
e"
                shift
        done
