The simplistic "listall" action implementation just uses _list() on the concatenation of active and done task lists. This has the following shortcomings:
- Task numbers shown for archived tasks from done.txt are invalid.
- As the number of done tasks likely greatly outnumbers the number of active tasks, the task number padding is often larger than expected (e.g. 0005 instead of 05).
- Verbose output lists all tasks as originating from TODO, whereas it should differentiate between TODO: and DONE: sources.
The main challenge is to keep processing all tasks through a single pass of _list(), so that there is a single, unified sorting applied to all tasks. A custom AWK script sets all (originally invalid) task numbers from done.txt to "0", meaning "archived task".
The verbose message from _list() is replaced with a custom message that shows the tasks from todo.txt, done.txt, and totals.
Oh, and added tests for the previously untested "listall" action.
- _list() now shows the capitalized filename in place of 'TODO:'.
For example, listing garden.txt produces a output prefixed by 'GARDEN:'
This eliminates the ' from $FILE' part of the _list() output. All tests
were adjusted to match this new output.
