Yes, I know. But users should know what code use in the file. And cannot use
it as filter. However, it's not important. Here is another thing in djgpp.

  +0      5        pos.
  "FOO\r\nBAR\r\n" (opened by text mode)

  after `read (fh,buf,3)', it returns 3 and seek at 3
  after `read (fh,buf,4)', it returns 3 and seek at 4 but delete '\r'

It separates CR from LF. So I cannot found the difference from BUF
and cannot seek backward easily.
New version delete only CR before LF and check EOF(Ctrl+Z) by same pass.
