I thought when len == LARGE_PACKET_MAX,
this could trigger. Though on inspection of packet_read,
we already reject packets that have size LARGE_PACKET_MAX,
and the largest size allowed is LARGE_PACKET_MAX - 1.

I guess we can remove it altogether and still be future proof.
If we ever want to allow larger push options we either need to
have larger (variable sized) packets or a capability push-options-v2,
so I'll rip this check out.

This check was not about "option with lf at end\n", but rather we want to chop
off "option\nover\nmultiple\nlines" ?

Although as you remarked in another email, this would not pose a problem for
the shell variable, so we could also drop it to allow multi line
options. will do.
