- Improve bash completion for 'project:', 'depends:', and 'priority:'.
- 'projABC:' no longer expands (same for 'depends:' and 'priority:').
- 'proj:' only expands if abbreviation.minimum is less than 5
(same for 'depends:' and 'priority:' and for other values of
abbreviation.minimum).
- Unit tests for the above.
- Improved style and efficiency of Perl test code.
- Added alias expansion to feature log of bash completion script.
- Added comments to bash completion script.
