Perhaps "static int valid_remote_nick(const char*)" is needed?
I'd say we can limit it to something like:

static int valid_remote_nick(const char *name)
{
	if (!name[0] || /* not empty */
            (name[0] == '.' && /* not "." */
             (!name[1] || /* not ".." */
              (name[1] == '.' && !name[2]))))
		return 0;
	return !!strchr(name, '/'); /* no slash */
}
