>Description:
Can't write this:

$ports = {
    123,    # foo
    456,    # bar
    789,    # baz
}

npf.conf treats line break like `;', and supports `\' continuation lines but only if there's no comment.  It also doesn't like the trailing comma, which would be friendlier to M-x sort-lines.  So although the input can be broken into lines, they can't have comments or be reliably reordered:

$ports = {
    123, \ 
    456, \
    789 \
}

Yes, please!
