Hu? Who told you that nonsense? It's not true at all :-)
For sure this is true. You can try it your own: Write a little program that
reads characters from stdin via getchar. You never will get any backspace
characters and such things, and the characters of a line will not be sent
until you hit the return key.
Note: This is only true if stdin is connected to the "keyboard" (so the
Terminal handles the input). If you use pipes to link stdin to a file or
other streams, there is no line buffering for sure.

In which programs does it work, then?
In all my programs that get characters from stdin via getchar or scanf etc.
;-)
But perhaps there is some way for programs to prevent the line buffering of
the terminal. Hmmm, I think tcsh needs to do that to enable the "history"
(Cursor up/down).
