The comment contains:
# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sde1

which suggests that D-I created it and the bug is there, no? Looks like
in particular it comes from grub-installer although the root bug might
be in os-prober:

$ cat grub-installer/grub-installer
...
if [ -s $tmpfile ] ; then
        case $grub_version in
[...]
            grub2)
                if ! $chroot $ROOT which os-prober >/dev/null 2>&1; then
                        cat > $ROOT/etc/grub.d/30_otheros << EOF
#!/bin/sh
exec tail -n +3 \$0
EOF
                        cat $tmpfile >> $ROOT/etc/grub.d/30_otheros
                        chmod +x $ROOT/etc/grub.d/30_otheros
                        update_grub # propagate 30_otheros to grub.cfg
                fi
                ;;
        esac
        rm -f $tmpfile
fi
...

You can/should edit /etc/grub.d/30_otheros instead.
