42 or input from a pipeline.
48 'vi' is a text editor. More specifically, it is the One True
49 text editor <grin>. It does, however, have a rather steep
50 learning curve. If you are not already comfortable with 'vi'
51 you may wish to use something else.
53 config FEATURE_VI_MAX_LEN
54 int "Maximum line length in vi"
