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?
