That was a conscious decision and the whole point is to able to override them and reuse them. They should be part of the API IMHO as `default_options`. Thus way you can have different `msgmerge` and `xgettext` options if, for any reason whatsoever, they should differ. It's DRYier this way as well.

If you insist I can make them private or put them back into the task (but they won't be available to others that way). What do you say?
