Description:
------------
continue documentation says, "...continue execution at the beginning of the next iteration."

To me, the beginning would mean the top, where it began.

I noticed that continue takes you to the bottom of a do loop.  According to the documentation (as I read it), the attached code should go into an endless loop.  However, it exits just fine.

I noticed that bug #3073 'fixed' this issue.  ie, continue used to go to the top, now goes to the bottom.

Reproduce code:
---------------
$x = 0;
do
{
  if( $x == 0 )
    continue;

} while( $x != 0 );

Expected result:
----------------
An endless loop that eventually times out

Actual result:
--------------
Absolutely nothing
