changes needed to deal with git-annex bug

[joeyh]

Unfortunately, git-annex has a bug that affects git-annex-remote-googledrive. See http://git-annex.branchable.com/bugs/external_remote_export_sent_to_wrong_process/
git-annex-remote-googledrive supports exporttree=yes, so it is susceptable to that bug when used with an unfixed version of git-annex.

Since this could result in data loss (or at least the wrong content being stored on google drive for a file), it makes sense to guard against it by making changes to git-annex-remote-googledrive.

Probably the best way for you to fix this is to update it to send VERSION 2 where it currently sends VERSION 1. That will prevent it from being used with an old buggy git-annex.
