I have now confirmed this with a small shell script:

#!/bin/sh

pkg=$1

ungrafted="$(guix build --no-grafts -d $pkg)"
grafted="$(guix build -d $pkg)"

if [ $grafted = $ungrafted ]; then
    echo $pkg has no grafts
else
    grep "$ungrafted" "$grafted"
fi

It works for 'python-patiencediff', but fails for 'python-patch-ng',
both of which have no dependencies other than Python; but one uses
url-fetch and the other git-fetch.
