The root cause of this is the installer, which writes directly to 
settings.php.

I propose we move settings.php to settings-dist.php (or similar) and the 
installer can copy that and update rather than write to a file that is 
in CVS.

At the same time, I think we should do the same with .htaccess if we 
can, because often .htaccess needs to be modified locally, and it's 
annoying having to weed that out of patches too. Of course, that's a 
little more complex due to needing write permissions and all.
