Every 30 minutes, each open document with unsaved changes since its last version gets an automatic "Autosave" version (flagged `auto` in the file). The newest 20 autosaves are kept; older ones make room and user versions are never dropped for them. Runs of autosaves fold into one line in the Version history panel. New command version.autosave.
