... Okay this is stupid. Maybe something to deprecate/fix on the php-src side...

I looked at the commit history of output.c and the false check was originally added for ob_gzhandler() to signal to the output buffer to return the original contents of the buffer without actually copying it.
The true check was added during the redesign of the output API without any notes on why. Returning true does exactly the same as returning null or an empty string.

The aim of this PR is to document most details of output control / output buffering.
It adds three new pages to the
outcontrolbook:flush()and implicit flushing)I've checked all related user comments in the manual, and bugs, PR's and issues on
bugs.php.net,php-srcanddoc-en. Additionally, I've tested everything before I've added it to these pages (on the CLI and a web server) so everything on them at least"works on my machine".If accepted, these pages or sections of it could be linked to from other output control pages.
