The intention behind this is so that cut can be implemented as a small
state machine using just getchar, putchar, and a counter.
I wrote `lcut' first, then adapted it for `cut'.
This avoids
copying via a line buffer, and that implies there should be no line-length
limit.
zgetline has no line length limit.
