[Users] kranc checkout, GetComponents and GitHub repository

[Bruno Coutinho Mundim]

Hi,

when trying a fresh checkout of einsteintoolkit, I found the following
error message:

-----------------------------------------------------------------
   Checking out module: KrancNumericalTools/GenericFD
       from repository: http://github.com/ianhinder/Kranc.git
                  into: Cactus/arrangements
cwd = /home/bruno/tmp/test
git clone --depth 1 http://github.com/ianhinder/Kranc.git 
Cactus/git-repos/Kranc
shallow over http or ftp not supported
-----------------------------------------------------------------

...

   Unable to process KrancNumericalTools/GenericFD.



The option --depth 1 is not accepted by GitHub. I was able to clone it
without a problem otherwise. Do we really need this option in GetComponents?

Thanks,
Bruno.
