{- By default, haskell honors the user's locale in its output to stdout
- and stderr. While that's great for proper unicode support, for git-annex
- all that's really needed is the ability to display simple messages
- (currently untranslated), and importantly, to display filenames exactly
- as they are written on disk, no matter what their encoding. So, force
- raw mode.

- NB: Once git-annex gets localized, this will need a rethink. -}
