If BUSYBOX_FEATURE_EDITING is enabled, BusyBox's "ash" and "hush" shells
are doing something magical (using BusyBox's read_line_input() function)
when interactively editing a command line from a TTY. The shell's
built-in commands that use standard input (such as the 'read' command)
do not use this magic line editing, and rely solely on the stty
settings. The same applies to most external commands that can read from
standard input (including those implemented by busybox) unless they
implement their own readline-like functionality.
