------------------- - Gave the `add_line_to_file()` and `remove_lines_from_file()` functions `encoding` and `errors` arguments - Inserter instances can now be safely reused across multiple calls to `add_line_to_string()`/`add_line_to_file()`
0.2.0
------------------- - The `add` command now expands backslash escapes in `line`. - Gave `add` an `-L/--line` option for specifying the `line`, especially when it begins with a hyphen. - Gave `remove` an `-e/--regexp` option for specifying the `regexp`, especially when it begins with a hyphen.
