- * TODO:
- * - Add more regular expression support - search modifiers, certain matches, etc.
- * - Add more complex bracket searching - currently, nested brackets are
- * not considered.
- * - Add support for "F" as an input. This causes less to act in
- * a similar way to tail -f.
- * - Check for binary files, and prompt the user if a binary file
- * is detected.
- * - Allow horizontal scrolling. Currently, lines simply continue onto
