| The following haven't been tested mostly because I can't figure out how to do so. |
| diff --minimal |
| diff --horizon-lines |
| diff --speed-large-files |
| diff --show-c-function |
| diff --show-function-line |
| diff --starting-file |
| |
| diff -x | -X in combination with --ignore-file-name-case as the latter doesn't work due to a bug. |
| |
| diff3 -a |
| diff3 -T |
