The manual's wording is untouched since import in 1995, engine.c however
came to be in 2008 as "New display engine for systat" from canacar.
While characte erase (^h) works, word erase (^w) is not implemented and
line kill (^u) is supported but as ^g instead.
I see no value in documenting this either way, so remove the lines from
the manual but also support the actual line kill character for.
Feedback? OK?
