Help: `Work around a bug in Google Drive listing.
Normally rclone will work around a bug in Google Drive when using
--fast-list (ListR) where the search "(A in parents) or (B in
parents)" returns nothing sometimes. See #3114, #4289 and
https://issuetracker.google.com/issues/149522397
Rclone detects this by finding no items in more than one directory
when listing and retries them as lists of individual directories.
This means that if you have a lot of empty directories rclone will end
up listing them all individually and this can take many more API
calls.
This flag allows the work-around to be disabled. This is **not**
recommended in normal use - only if you have a particular case you are
having trouble with like many empty directories.
