1823/// which are not maintaining the entire terminal state intact.
1824///
1825///
1826/// The library
1827///
1828/// * does not increment inner grid cursor's _lines_ on `input` calls
1829/// (but displaying the lines correctly and incrementing cursor's columns)
1830///
1831/// * ignores `\n` and \r` character input, requiring the `newline` call instead
1832///
1833/// * does not alter grid state after `newline` call
1834/// so its `bottommost_line` is always the same additions, and
1835/// the cursor's `point` is not updated to the new line and column values
1836///
1837/// * ??? there could be more consequences, and any further "proper" streaming from the PTY might bug and/or panic.
1838/// Still, subsequent `append_text_to_term` invocations are possible and display the contents correctly.
1839///
1840/// Despite the quirks, this is the simplest approach to appending text to the terminal: its alternative, `grid_mut` manipulations,
1841/// do not properly set the scrolling state and display odd text after appending; also those manipulations are more tedious and error-prone.
1842/// The function achieves proper display and scrolling capabilities, at a cost of grid state not properly synchronized.
