What .gitignore to use for KiCAD projects?

KiCAD generates a lot of backup-like files, for example MyPCB.sch-bak that should be ignored by git and don’t need to be committed to the repository.

This is the .gitignore file I use to manage my KiCAD projects:

*-bak
*-backups
*-cache*
*-bak*
_autosave*
\#auto_saved_files\#

Note that TechOverflow’s KiCAD project initialization script automatically generates this.gitignore.
