Summary: When repo is used with git, 'clang --version' option does not display the correct revision information (i.e. git hash on TOP) as the following: clang version 6.0.0 ---> clang version 6.0.0 (clang version) (llvm version) This is because repo also creates .git/svn folder as git-svn does and this makes repo with git uses "git svn info" command, which is only for git-svn, to retrieve its revision information, making null for the info. To correctly distinguish between git-svn and repo with git, the folder hierarchy to specify for git-svn should be .git/svn/refs as the "git svn info" command depends on the revision data in .git/svn/refs. This patch in turn makes repo with git passes through to the third macro, get_source_info_git, in get_source_info function, resulting in correctly retrieving the revision information for repo with git using "git log ..." command. This patch is tested with git, svn, git-svn, and repo with git.
