Not close enough: his 2000 patch just changed indentation.  I think the
origin of this problem is:

   revno: 6577
   committer: rms
   branch nick: HEAD
   timestamp: Thu 1994-03-03 05:50:31 +0000
   message:
     Include unistd.h.
     (pty_max_bytes): New variable.
     (send_process): Send an eof after each pty_max_bytes bytes.

And clearly there was a good reason for that.  I don't know enough about
PTY programming to know what we should do.

Agreed (if at all).
