Subversion diffs formatted with diff wiki processor are double-escaped

[Bruce Christensen <trac@…>]

Subversion diffs in tickets, wiki pages, and attachments rendered using the diff processor are double-escaped. Examples:

• Ticket: ticket:2432
• Attachment: attachment:ticket:2432:web_ui.py.patch​
• Wiki: no current wiki pages use the diff processor, but I confirmed on the SandBox page that it is indeed broken.

For example, this text:

{{{
#!diff
Index: test.txt
===================================================================
--- test.txt      (revision 257)
+++ test.txt      (working copy)
@@ -25,6 +25,7 @@

 this is more text
+  this is indented text with funky chars: <>"' and funky           spacing

}}}

is rendered as:

test.txt

@@ -25 +25 @@

Note that changesets shown in TracBrowser don't have this problem. Also, non-Subversion diffs are fine. For example, this text:

{{{

Yeah, just noticed that too.

Should be fixed in [2730], [2731].
