[PATCHv6 0/8] --dirstat fixes, part 2

Hi,

Here's version 6 incorporating Junio's feedback regarding tests, error messages, and i18n. The following patches have changed:

 - 1/8: Added test: 'various ways to misspell --dirstat'

 - 3/8: Added a couple of more misspellings to the above test

 - 7/8: Improved error message handling, and tests covering error messages

 - 8/8: New patch marking dirstat error messages for translation.

The new 8/8 patch WILL NOT COMPILE until the topic branch is merged with an i18n/gettext-aware branch (i.e. where _() and test_i18ngrep is present).

Have fun! :)
