Title: BUG: No prompt for session auto-load when unloaded buffers exist.

When file marks (e.g. `'A`) cause unloaded buffers to exist on startup, the question for session auto-load isn't brought up.

`bufnr('$') == 1` isn't a correct check; one needs to go through all existing buffers and check for listed ones that aren't the current one.
