safe_mode cause exec command to parse all arguments after the command as one argument (in quote?)

Is this a bug? is it documented somewhere?

exec("echo x | echo y",$output);
$output=implode(',',$output);
echo "output is: $output"
?>

Expected result:
----------------
safe_mode off output is: y

Actual result:
--------------
safe_mode off output is: y
safe_mode on output is: x | echo y

Yes, it's a feature. Couldn't find it documented anywhere.
Reclassifed as documentation problem.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

I added a warning below the other safe_mode note. Thanks.

This should also be mentionned in the other functions of ref.exec. Maybe with an entity ?

Added the entity kennyt@php.net created to passthru() and system().

You didn't fix nothing here... I added an entity yesterday :

http://news.php.net/article.php?group=php.doc&article=969358998

This bug report is about the problem reflected by &warn.sm.exec; It's already in exec() and system() man page, but still need to be added elsewhere.
