今天突然发现KCN2.70的自动换行好象有些问题，断行总是断在汉字中间，
找了一下辕马，在edit.c中有这么一段：

/* Add By KCN for auto crlf*/
void
autolfline(line,fp)
char* line;
FILE* fp;
{
......
                  if (curlinelen>73)
                  {
                        if (dbchar)
                        {
                          fwrite(p1,1,p2-p1-1,fp);
                          p1=p2-1;
                        }
                        else
                        {
                          fwrite(p1,1,p2-p1,fp);
                          p1=p2;
                        }
                        dbchar=0;
                        fprintf(fp,"\n");
                        curlinelen=0;
                  }
                  if (dbchar)
                     dbchar=0;
                  else
                  if (*p2&0x80)
                    dbchar=1;

好象就是这段控制断行的？可是我没怎么看懂，它从第一列开始检查的还是只是简单的
从73列断行？如果是后者，那么如果行内有半角字符不就歇菜了？

哪位给我解惑？多谢！
