[TYPO3-core] Flushing output buffers before sending thumbnails

[François Suter]

Hi all,

I just pushed a rather trivial patch [1] that solves an annoying issue 
[2]. But I know that there have been various issues with flushing 
buffers before and I was just wondering if anyone found this patch wrong 
from a conceptual point of view.

I know it's also a question of having clean files included, with no 
opening or trailing blank lines, but this is such a common hazard that I 
figure it's safer to flush the buffers, especially in such a simple case 
as this one (i.e. read an image file and throw its content down the HTTP 
request's throat).

Opinions?

Cheers
