+I noticed when generating my wiki that all of my RSS feeds were
+getting regenerated even when I edited only a page that did not affect
+any feed.
+
+I found that the problem only occurs in the presence of a file that
+contains \[[inline pages="*"]].
+
+Here's a short script for replicating the bug. Just cut and paste this
+to a shell, (it will only muck in a new /tmp/ikiwiki-test directory
+that it will create):
+
+	cd /tmp
+	mkdir ikiwiki-test; cd ikiwiki-test; mkdir src
+	echo '[[inline pages="blog/*"]]' > src/myblog.mdwn
+	mkdir src/blog; echo "A blog entry" > src/blog/entry.mdwn
+	echo 'use IkiWiki::Setup::Standard {
+		srcdir => "src",
+		destdir => "output",
+		url => "http://example.com",
+		templatedir => "/dev/null",
+		underlaydir => "/dev/null",
+		rss => 1,
+		wrappers => [],
+		verbose => 1,
+		refresh => 1
+	}' > setup
+	ikiwiki --setup setup
+	ls -l --time-style=full-iso output/myblog/index.rss
+	echo "not a blog entry" > src/not-a-blog.mdwn
+	ikiwiki --setup setup
+	ls -l --time-style=full-iso output/myblog/index.rss
+	echo '[[inline pages="*"]]' > src/archives.mdwn
+	ikiwiki --setup setup
+	ls -l --time-style=full-iso output/myblog/index.rss
+	echo "still not blogging" >> src/not-a-blog.mdwn
+	ikiwiki --setup setup
+	ls -l --time-style=full-iso output/myblog/index.rss
+
+Here's the tail of the output that I see for this command:
+
+	$ echo "not a blog entry" > src/not-a-blog.mdwn
+	$ ikiwiki --setup setup
+	refreshing wiki..
+	scanning not-a-blog.mdwn
+	rendering not-a-blog.mdwn
+	done
+	$ ls -l --time-style=full-iso output/myblog/index.rss

+	$ echo '[[inline pages="*"]]' > src/archives.mdwn
+	$ ikiwiki --setup setup
+	refreshing wiki..
+	scanning archives.mdwn
+	rendering archives.mdwn
+	done
+	$ ls -l --time-style=full-iso output/myblog/index.rss

+	$ echo "still not blogging" >> src/not-a-blog.mdwn
+	$ ikiwiki --setup setup
+	refreshing wiki..
+	scanning not-a-blog.mdwn
+	rendering not-a-blog.mdwn
+	rendering archives.mdwn, which depends on not-a-blog
+	done
+	$ ls -l --time-style=full-iso output/myblog/index.rss
+	-rw-r--r-- 1 cworth cworth 459 2007-06-01 06:34:38.000000000 -0700 output/myblog/index.rss
+
+It looks like the rendering of archives.mdwn is also silently
+generating myblog/index.rss.
