+Subject: [PATCH] Make mistune.util.escape_url less aggressive
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds ';', '!', and '$' to the set of characters which will be
+passed unmolested by escape_url.  These are all in RFC 3986 reserved
+character list — that is to say: escaping these may change the meaning
+of a URL.
