Yes. This will cause errors on the next update, so this is only half a  
solution:

Files for which a *.dist version is distributed should not be touched,  
but the imp/config/hooks.php is an exception here (see the remaining  
messages in this thread, where it is explained why). So far I have  
prevented Horde from touching this file by setting the immutable bit,  
but apparently I forgot to set it the last time I modified the contents.
