Description:
------------
The "." in open_basedir is always getting translated to directory portion of SG(path_translated).

This behaviour is fine for a CGI or mod_php5 module. But not for a CLI where "." != the directory of the script 



Reproduce code:
---------------
1)Keep a script in /home/kameshj/scripts/test.php
2)Keep a file k.txt with some content in /home/kameshj
3)Keep open_basedir as "."
///home/kameshj/scripts/test.php
<?php
echo getcwd();
echo "\n";
var_dump(file_exists("/home/kameshj/k.txt"));
?>

Run the above php from the working directory /home/kameshj

php /home/kameshj/scripts/test.php

Even though we have "."(/home/kameshj in this case) as open_basedir and we access /home/kameshj/k.txt file_access will still fail as "." is taken as /home/kameshj/scripts

Expected result:
----------------
/home/kameshj
bool(true)

Actual result:
--------------
/home/kameshj
bool(false)
