[TYPO3-core] RFC #12189: Add API functions for cleaning and flushing output buffers

Hi,

I'm not an expert in this, but experience shows that this is true ;-)

I now have tons of warnings like:

Core: Error handler (BE): PHP Warning: Cannot modify header information 
- headers already sent by (output started at 
/usr/local/src/typo3/TRUNK/t3lib/class.t3lib_div.php:5774) in 
/usr/local/src/typo3/TRUNK/t3lib/class.t3lib_div.php line 5776

when running CLI scripts. Line 5776 of t3lib_div is in method 
flushOutputBuffers() and reads:

header('Content-Encoding: None', TRUE);

So it would seem like this line should be removed. Can anyone confirm?

Cheers
