I'm using this to protect files from being accidentially being edited 
(like when kwin yet again fails to do focus follows mouse and I can't 
figure out what happened after I started typing). Such files usually 
contain some kind of notes, like how to create a selinux module.

So I sometimes do want to edit these files to update them as I keep 
learning.  Having to change the very file permissions for this would 
work, though it would be rather awkward.
