Different operation systems (Unix vs. Windows) use different line ending types. It can easily happen that users from different systems edit files and replace all line endings of a file with the system specific version. This screws up diffs and makes merges harder. Git can normalize line endings for specific files and avoid this problem. Binary files should be marked to avoid accidentally normalization.
