Ignore files generated by OS X that might appear on external disks:
  .Spotlight-V100
  .Trashes

Hopefully comments look better now.

Improved CodeIgniter .gitignore to support an system directory in a different location to the default install. Fixed database.php ignore rule. The application directory can be moved to any location and the ignore will still operate

Removing:
- static/uploaded/**/* since there is no default
  for upload paths (configurable)
- *.mo because it's a best practice to keep them
  close to the po files and update before release
- *.pyc since that's covered by the Python gitignore file

Adding:
- local_settings.py because it's a best practice
  for Django projects (next to settings.py)

According to current man pages of git-config there is no = to set
the config value.

This is common amongst ruby projects in eclipse.

Unless full paths are used .gitignore, all matching files and folders will be ignored, however deep they are in the repo.

For example, ignoring log/* doesn't just ignore all log files, but also files such as lib/project/log/awesome_logger.rb.  It's a mistake I've made a couple of times but never seemed to have learned from.
