I assume you refer to the discussion in section 7.9.3 (Library,
Input/Output <stdio.h>, Files). If stdin is interactive, it cannot be
fully buffered in a conforming implementation. There is some wording
about how characters "are intended to" be transmitted to and from the
host environment under the various buffering schemes, but that part
seems to be very careful not to promise anything.

If the Standard was intended to bind conforming implementations on the
exact behaviour of line buffered input from terminals, it should come
out and say so.
