Patch for supporting git-alternates

[David Yen]

Hello,

I would like to submit a simple patch to support git alternates when
running GetRepositoryPath.

------------------------------------------
Support git alternates when obtaining remote repository paths.

When git alternates are being used, this simply goes into the git
alternates directory before running the "git remote" command.
