This is completely analoguous to commit
633183b5d1c2.
Similar code called from __lookup_name is not affected because it checks
that the line contains the host name surrounded by blanks.
if ((p=strchr(line, '#'))) *p++='\n', *p=0;
for (p=line; *p && !isspace(*p); p++);
if ((p=strchr(line, '#'))) *p++='\n', *p=0;
for (p=line; *p && !isspace(*p); p++);
*p++ = 0;
if (__lookup_ipliteral(&iplit, line, AF_UNSPEC)<=0)
continue;
*p++ = 0;
if (__lookup_ipliteral(&iplit, line, AF_UNSPEC)<=0)
continue;
