Well, that's in fact the problem. The solution is to use RewriteCond:

RewriteEngine On
RewriteCond %{QUERY_STRING} ^id\=P([0-9]+)$
RewriteRule index\.php http://freedomsight.net/index.php?p=%1
[R=permanent,L]
RewriteRule index.php http://freedomsight.net/ [R=permanent,L]

The 2nd RewriteRule catches URLs with no "query string".

Other URLs, once I've wiped out the blog, I don't want to redirect -- why
send the comment spambots to the new place? (They'll find it soon enough
anyway, unfortunately.)
