- Added unit tests for bug 819, on behalf of Matt Kraai.
- Created a new, single test for cleanup that replaces 6. It's makes
for shorter unit tests, and adds less test count inflation. Over
time, all tests should be modified in a similar way. This will
probably cut the total number of unit tests in half, but that's not
the important metric.
- Corrected all unit tests that used the old syntax "task done 1" to
use the new syntax "task 1 done". Similarly, "task 1 ..." is now
"task 1 modify ...".
