Redmine

This is not technically a defect but the intended behavior of the RedCloth library. I'm investigating what the options are to make this a configurable option as a patch to RedCloth as I don't think this is what the vast majority of users would expect to happen. However, if you'd like to directly patch RedCloth as a complete hack, the following patch to lib/redcloth3.rb will work (though it's obviously pretty messy):

diff --git a/lib/redcloth3.rb b/lib/redcloth3.rb
index f4c6244..3948931 100644
--- a/lib/redcloth3.rb
+++ b/lib/redcloth3.rb
@ -308,6 +308,7 @ class RedCloth3 < String

Indeed, it looks like a intentional behavior for textile parsers (this occurs also with http://www.textism.com/tools/textile) although I can't find anything in any documentation.
