Impossible to ignore several files

[NumEricR]

Hi,
Firstly I want to thank you for your work: it's really cool to generate documentation within SublimeText!

Unfortunately I've got a problem with this package. I want to ignore some specific files but it doesn't work (It's ok when trying to ignore only one file).
I use the "additional_args" parameter that way but I also tried to use "-i":

"additional_args": {
    "--ignore": "directory/file1.php,directory/file2.php"
}

and the generated command line is:

phpdoc --ignore=directory/file1.php,directory/file2.php -d /PATH/TO/MY/PROJECT -t /PATH/TO/MY/PROJECT/build/api/ -i /PATH/TO/MY/PROJECT/build/api/

If I modify this command to remove the last -i parameter it works!
