    scripts/git: Remove a duplicate practracker call from the pre-push hook
    
    The pre-push hook already calls the pre-commit hook, which calls
    practracker.
    
    Also update the script comments to avoid similar issues in future.
    
    Fixes bug 31462; bugfix on 0.4.1.1-alpha.

+    - Our pre-commit git hook now checks for a special file
+      before running practracker, so that practracker only runs on branches
+      that are based on master. Since the pre-push hook calls the pre-commit
+      hook, practracker will also only run before pushes of branches based
+      on master.
       Closes ticket 30979.
