Hit DEL and you'll see the need. (Besides it is
an unexpected side effect not evident from the
function name.)

Second, you also kill the prompt string this
way. Sure, it returns with RET, but this isn't
how one would expect clear to work. It should,
IMO, work just like in a VT with the state
unchanged WRT read-only, and with the prompt
intact, only the material removed!

Thrid, with `kill-region', the material ends up
in the kill ring. Unclear if this is intuitive
or not?
