improve git repository 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. [ruby-core:74759] [Bug #12239] * 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 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@54468 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
