Description:
------------
In order to write a bash autocompletion program using php, you need two 
simple files.

1. bash script
2. php file processing the command and printing it

In this case, the autocomplete works but a "tab" is appended to the output 
making it useless

The php script contains a simple "echo".
If I print the echo in python or ruby, it works properly (no tabs appended) and 
each time I press tab the command is printed.
That's how it should work for php as well.

Test script:
---------------
scriptPath='/home/hassen/workspace/scripts/bin/test.php'

_dda()
{
        local cur
        COMPREPLY=()
        unset COMP_WORDS[0] #remove "j" from the array
        cur=${COMP_WORDS[*]}
        IFS=$'\n\n' read -d '' -a COMPREPLY < <($scriptPath --completion "$cur")
        return 0
}
complete -F _dda dda

alias dda=$scriptPath

----
test.php

<?php
echo "hello";
?>

Expected result:
----------------
"hello" should be appended each time I press "TAB"

Actual result:
--------------
Tabs are appended
