more on read_client_block

[ra...@vex.net]

Ok, I managed to get read_client_block() to work for me, but I had
to add this line before the call:

        php_rqst->remaining = length + 1;

It seems odd that I have to manually set the r->remaining value.
Why isn't this set already directly from the content length?

Perhaps I don't understand chunking properly.  Could someone explain
it in 25 words or less?
