Rather bad bug in 4.2.0 zle-line-init

[Bart Schaefer]

Make any sort of mistake in zle-line-init, and the editor goes into an
infinite loop.

E.g. (be sure you can kill this shell from somewhere else):

zle-line-init() {
  setopt localoptions match
  echo not[a]pattern(that)matches{anything}
}
zle -N zle-line-init
