I believe I have encountered a bug in Textile 2.0.4 bundled with Movable Type 4.01.
When an entry is formatted with Textile, two dashes (--) are no longer marked up as an em dash. Instead, the dashes are left alone and are output as "--" instead of the HTML entity for an em dash (&mdash or —).
In previous relases of Textile (<2.0.2) and Movable Type (<3.34), this wasn't a problem, but is a symptom that can be reproduced using Textile 2.0.4 and Movable Type 4.01.
As far as I can tell, the problem occurs in all entry fields (I tested both MTEntryBody/mt:EntryBody and MTEntryMore/mt:EntryMore). I also have the "Replace Word Chars" option in Preferences > Blog Settings > Entry disabled ("Smart Replace" is set to "No substitution").
I'm running Apache v2.0.52 (on CentOS) with Perl v5.8.5, PHP v4.3.9, and MySQL v4.1.20.
Can anyone confirm this behavior to be a bug, and if so is there a fix available?
