+Text::Markdown obfuscates email addresses in the href= attribute and in the text.
+Apparently this can't be configured.
+
+HTML::Scrubber doesn't set `attr_encoded` for its HTML::Parser, so the href= attribtute is decoded.
+Currently it seems it doesn't set `attr_encoded` for good reason: so attributes can be sanitized easily,
+e.g. as in htmlscrubber with `$safe_url_regexp`.
+This apparently can't be configured either.
+
+So I can't see an obvious solution to this.
+Perhaps improvements to Text::Markdown or HTML::Scrubber can allow a fix.
+
+One question is: how useful is email obfuscation?
+Don't spammers use HTML parsers?

+I've [[patch]]ed mdwn.pm to prevent Text::Markdown from obfuscating the emails.

+Suppose a wiki has a source page a.mdwn, which is then moved to a.wiki.
+(Suppose both the mdwn and wikitext plugins are enabled, so this changes how "a" is rendered.)
+Currently, when the wiki is refreshed, ikiwiki doesn't notice the change
+and the page is not rebuilt.
+
+I have a [[patch]] that fixes this.
+The relevant commit on [my Github fork of ikiwiki](http://github.com/gmcmanus/ikiwiki/) is:

+    b6a3b8a683fed7a7f6d77a5b3f2dfbd14c849843
+
+The patch (ab)uses`%forcerebuild`, which is meant for use by plugins.
+If, for some reason, a plugin deletes the page's entry in `%forcerebuild`, it won't be rebuilt.
+
+This patch uncovers another problem.
+Suppose a wiki has a source page "a" (no extension)
+which is then moved to "a.mdwn" (or vice versa).
+ikiwiki fails when trying to create a directory "a" where there is a file "a"
+(or vice versa).
+
+The same problem occurs if both "a" and "a.mdwn" exist in the wiki.
