I have been unable to get the :match feature of columnview dblocks to work.
I need it because I want to filter headlines by tags that I used to
identify Scrum stories in a particular sprint. I have basically tried every
conceivable version of :match such as :match "Sprint4", :match "Sprint4",
:match ":Sprint4:", :match "TAG=\":Sprint4:\"", and match:
"TAG=\"Sprint4\"". Basically, nothing works.

* Scrum Summary
