I agree that in the absence of an option, getting the whole buffer
rather than defaulting to line=1 (and blocking) is preferred.  This
change should be "safe" to make.

As I understand it, these values are minimums.  If you want 10 bytes
you might get 20 but you'll always block until there are 10 available
(or the timeout occurs).

Thanks for your help,

Brandon
