Either by specifing several -c parameters or only one -c parameter with a comma separated value. One could for example be for the official arch packages and one for the aur.

Please don't use basename(1) when bash can do this for us. Your quoting is wrong, too (you'd need "$(basename "$name")"). What you meant to write was: printf '%s (%s):\n' "${name##*/}" "$arch"

Again with the lack of quoting... <(printf "$PWD/%s\n" *.pkg.tar?(.+([^.])) | pacsort --files | I'm somewhat concerned about this because we're injecting a path into the format string (yes, we've done this elsewhere and it's equally concerning). Since it's pre-existing, we can probably ignore this bug for now. Could you leave a TODO to address it, though? It's probably sufficient to just escape % and \ chars in $PWD, but it needs testing.
