You can get a list of files in backup arrays that you've modified with
`pacman -Qii | grep '^MODIFIED'`, which won't include configuration
files that you've created yourself but you can track those down by
printing out a list of unowned files in /etc. Anything not either in a
backup array or unowned would just be overwritten on package updates
anyway.
