[[tag patch]]

This lets the site administrator have a `.htaccess` file in their underlay
directory, say, then get it copied over when the wiki is built. Without
this, installations that are located at the root of a domain don't get the
benefit of `.htaccess` such as improved directory listings, IP blocking,
URL rewriting, authorisation, etc. 

> I'm concerned about security ramifications of this patch. While ikiwiki
> won't allow editing such a .htaccess file in the web interface, it would
> be possible for a user who has svn commit access to the wiki to use it to
> add a .htaccess file that does $EVIL.
