* List all current option flags
* Provide descriptions for every flag
* Pass the `task -l` descriptions as descriptions for the task completions
+ The prior logic had 4 invocations of sed and 1 of awk, and only kept the
task name
+ Do all filtering in zsh without forking (except for `task` itself)
* When `--taskfile` is used, complete tasks from _that_ file
+ And otherwise, enable completions if only the `.dist` variant files are
present
* Ensure mutually exclusive options preclude each other
+ the `+ '(groupname)'` clause defines this
* Fix `--dir` to take directories, not files
Added a --dry-run flag that compiles and steps through each task, but does not execute them. The commands that would have been run are printed. See #125.
