Description:
------------
The function ereg_replace() "duplicates" the replacement string when the match string is ".*".

Example: 

- input "BLABLA"
- match ".*"
- replace "TEST"

Output is "TESTTEST", although it would be expected to be "TEST".

Reproduce code:
---------------
<?

$source = "BLABLA";
$match = ".*";
$replace = "TEST";

print ereg_replace($match, $replace, $source);
print "\n";

?>

Expected result:
----------------
only a single "TEST" (as this is the case with sed, too), because i expect ".*" to have maximum greediness.

Actual result:
--------------
see example code. produces "TESTTEST". This happens in all PHP versions i have access to (older PHP4, current PHP4 and PHP5).

Using "^.*" as match, or ".+" works as expected.
