Large repository clone error

[Ryan Hartzog]

Thanks for the help.  I updated to the latest rev and started from scratch
since this was a new repo anyhow.  Instead of trying to commit and push all
of it at the same time I used smaller chunks at a time.  Took more work, but
was able to check validity of repo with each push. Not sure which variable I
changed that helped, but it is working well and I appreciate the help.
