uses of svn:ignore ?

[Michaël]

Hi all,

I want to ignore a config file located in my working copy at 
./application/config/config.php . So, in command-line I type the following :

$ cd application/config
$ svn propset svn:ignore config.php .
property 'svn:ignore' set on '.'
### and I can check
$ svn propget svn:ignore .
config.php

But, if check status, I see I modified config.php :
$ svn st
M       config.php


How can I fix that ?

Thanks,
Michaël
