Description:
------------
In CLI implicit_flush is default to 1, however when using the reproducing code implicit_flush is not used but the value of output_buffering is taken into account. If output_buffering is 0 in php.ini then everything is fine but if in php.ini the value is 4096 (or probably some value that is > 0) the output is buffered no matter it's in CLI mode. Evenmore, flush()-ing also has no effect as can be seen in the actual output.
This behaviour exists both in PHP_4_3 and in HEAD.



Reproduce code:
---------------
php -r 'echo printf("phpversion=%s\noutput_buffering=%s\nimplicit_flush=%s\n", phpversion(),ini_get("output_buffering"), ini_get("implicit_flush"));flush();$a="fubar\n"; echo $a; fubar_func();'

Expected result:
----------------
As can be seen on execution 1 and 2 of the actual result PHP dies after a fatal error of calling undefined function and after that the output which is output before the call is feed to the console.
Execution 3 and 4 show the behaviour which is expected to be normal but is only valid when output_buffering is 0 (implicit_flush as it can be seen is not taken into account).

Actual result:
--------------
Exection 1:
PHP Fatal error:  Call to undefined function fubar_func() in Command line code on line 1

output_buffering=4096
