.gitignore behavior on Mac

Shouldn't this be valid? I would expect to NOT see the core/inc/config.inc.php in the "git status" output...

Peters-MacBook-Air:dt-git plauri$ cat .gitignore .buildpath .project .settings/ web/pjotr.php core/inc/config.inc.php dt_error.log process_wrapper.sh

Peters-MacBook-Air:dt-git plauri$ git status # On branch local/DT-7_gantt # Changes not staged for commit: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: .gitignore # modified: core/inc/config.inc.php # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # out.ionel # tree.py no changes added to commit (use "git add" and/or "git commit -a") Peters-MacBook-Air:dt-git plauri$
