Exoskeletal "enhancement"? Is there any rationale for making the
ASCII behavior different from the EBCDIC?

In fact, "setvbuf( stdout, NULL, _IONBF, 4096 );" repairs the lazy buffering.
Surprisingly, _IOLBF lacks that effect. Feels like a bug?
loc. cit.:
_IOLBF
Line buffering is used for text stream I/O and terminal I/O. The buffer is
flushed when a newline character is used (text stream), when the buffer
is full, or when input is requested (terminal). The value for size must be
greater than 0.
Hmmm. On a hunch, I added "...\025" to the end of each format string.
Now, the buffer gets flushed, even with _IOLBF. Ah! It's that kind of bug.
Guess what I hate!
Thanks,
