Literate programming in C: if(0)

I am not a C expert, but some code in libressl 2.3.2
(latest as of now) and openssl 1.0.1p (and probably later) 
looks weird to me.

The code in libressl is in ssl/s3_clnt.c

984:  if (CBS_len(&cert_list) < 3)
         goto truncated;

1657:     if (0) {

The weird stuff is "if (0)".

Very similar stuff is in openssl.

Asked three C coders about it.

Two of them said "this sucks much".

One said "very nice idea!", denying joking.
