Bug#954319: libreoffice: reorder libreoffice-core-nogui dependency in -nogui variants

[Jochen Sprickerhof <jspricke@debian.org>]

Source: libreoffice
Version: 1:6.4.2-1
Severity: wishlist

When installing libreoffice-writer-nogui, libreoffice-core is selected:

# apt-get install --dry-run --no-install-recommends libreoffice-writer-nogui | grep libreoffice-core
  libreoffice-common libreoffice-core libreoffice-style-colibre
  libreoffice-common libreoffice-core libreoffice-style-colibre
Inst libreoffice-core (1:6.4.1-1+b1 Debian:unstable [amd64])
Conf libreoffice-core (1:6.4.1-1+b1 Debian:unstable [amd64])

because it's dependency is preferred:

# apt-cache show libreoffice-writer-nogui | grep libreoffice-core
Depends: libreoffice-base-core (= 1:6.4.2-1), libreoffice-core (= 1:6.4.2-1) | libreoffice-core-nogui (= 1:6.4.2-1), [..]

Reordering this to libreoffice-core-nogui | libreoffice-core should use
the -nogui variant by default.

I can provide a patch if needed.
