Bug#1111291: libconfig-model-dpkg-perl: Unknown fields have their order randomized

Package: libconfig-model-dpkg-perl
Severity: minor

Hi,

When `cme fix dpkg-control` is applied to a `debian/control` file with 
fields that `cme` does not know about, `cme` orders them at the bottom 
of the stanza (at least for the `Source` stanza). So far so good.

However, the order is not consistent between runs. That is, if you start 
with a `debian/control` that can be will be reformatted, run `cme fix 
dpkg-control`, note the field order as O1. Then reset the 
`debian/control` (git restore -- debian/control), run `cme fix 
dpkg-control` and note the new field order as O2.

I expected O1 to equal O2, but it does not when there are multiple 
unknown fields. This can trigger unnecessary edits such as via 
`routine-update` (which uses `cme fix dpkg-control`).

Best regards,
Niels
