RFC: Sort tarballs created by the src-release.sh script

[Nick Clifton]

Hi Guys,

   Right, here is the latest and greatest - and hopefully last - version
   of the patch.  I added a parseable string to the --mtime option and a
   comment explaining why these options are being used.

   Any more comments/suggestions ?

Cheers
   Nick
