Can't enhance Subject display

In case it's not clear what's going on...

The new parser for Subject renames "blob" to "list-tag" and adds support for a second field in square brackets named "topic-tag" to capture a feature of some mailing lists. The parser is clearly working, because the header pane is showing all 5 tokens correctly. The Subject column of the messages list is doing something entirely unclear, probably because I don't really understand the syntax of the formatString, and merely extended the pattern used in the stock outlineColumns file.

This ticket can be closed/ignored, as I have resolved the problem.

Fun MailMate Trivia: If you put outlineColumns.plist in Resources/ instead of Resources/MmMessagesOutlineView/ it isn't inert, but it does not work right.

(Cannot seem to see in the code that Resources/outlineColumns.plist would be inert, but maybe I'm missing something. Sorry about the very late response on this ticket.)
