 Sure, but in that case you can simply use isatty() to distinguish the
 special treatment. What I mean is that you can only call watch(8) by
 passing the TTY used on the command line.

 Also I see you've simplified the code that dynamically scales the input
 buffer size. Though I think that's a good idea, I do think we should
 increase BUF_SIZE to something higher. Setting it to 4 KB or something
 shouldn't harm, right?
