improve git repository detectionfix/git-worktree-detection
* configure.in (AC_CONFIG_FILES): $srcdir/.git can be a file pointing the real git_dir, such as when the git working tree is a "linked working tree" (a working tree created by git-worktree). So use git-rev-parse --git-dir to check if $srcdir is the top-level of a git repository, not just checking if the $srcdir/.git directory does exist or not. * tool/change_maker.rb: use tool/vcs.rb to detect VCS. This used to have its own VCS detection code, while we have tool/vcs.rb. * tool/vcs.rb (detect): remove code duplication
