- Addressed bug #804 by allowing rc.hyphenate to control whether hyphens are
inserted when long lines are broken. This may help prevent xterm from
mis-parsing URLs in task annotations, when wrapped (thanks to Yann Davin).
- Added unit tests.
- Changed the ::measure and ::render methods from pure virtual to
virtual.
- Fixed bug where recur.indicator used the length of the indicator
instead of the indicator.
- Implemented ColString.{h,cpp} to support generic Views based on
strings, not tasks.
- Implemented newly virtual Column:: methods.
