Tip: You can check that in seconds when you have set up your environment with a 'git worktree', one worktree for each active freeciv branch. Apply the patch to one branch in one worktree, and quickly cherry-pick it to other branches in other worktrees.

There's an example work setup in: https://github.com/freeciv/freeciv-environments/blob/main/buildsetup/meson_dir_hierarchy_setup.sh
