Dear Maintainer,

When running yamagi-quake2 version 8.50+dfsg-1 on trixie, with the full
Quake 2 data set installed with game-data-packager, the Q2DMx set of
maps (maps intended for deathmatch play) are not included in the
"Initial map" selection. This makes these maps unplayable on this
version of yamagi-quake2.

Version 8.20+ctf1.09+dfsg-1 of yamagi-quake2, from bookworm, does not
exhibit this behavior; the Q2DMx maps are included in the "Initial map"
selection. Thus, holding yamagi-quake2 and yamagi-quake2-core at this
version is an effective workaround.

To reproduce bug behavior:
- Install yamagi-quake2 version 8.50+dfsg-1 (from trixie/sid)
- Install quake2-full-data with game-data-packager
- Run /usr/games/quake2
- Select Multiplayer, then Start Network Server
- Observe that the first map offered is Outer Base, BASE1, and not The
  Edge, Q2DM1
- Right-arrow through the Initial Map selections and observe that no
  Q2DMx maps are offered

To reproduce intended/desired behavior:
- Install yamagi-quake2 version 8.20+ctf1.09+dfsg-1 (from bookworm)
- Install quake2-full-data with game-data-packager
- Run /usr/games/quake2
- Select Multiplayer, then Start Network Server
- Observe that the first map offered is The Edge, Q2DM1
