When to update the xi-editor submodule?

[mmatoszko]

Since xi-editor is a submodule of xi-mac now, we might need to establish a process of updating the commit of the subproject in the xi-mac repo.

If the subproject commit hash won't get updated people who clone the project using
git clone --recurse-submodules https://github.com/xi-editor/xi-mac might be using older version of xi-editor, and this might cause some unexpected issues.

Yep this is a good question.

• We could say that any PR to xi-mac should update xi-editor if it's behind
• We could update xi-editor 'as needed', say every week or so

Certainly any time feature support is being added to xi-mac, the xi-editor revision should be updated to include the new feature.
