Fix tab/space inconsistency
Merge pull request #85 from pnorman/patch-2

Fix tab/space inconsistency
Update autoconf-archive scripts from upstream.
User data was not being reset by anon.

The data selection was updating the user information if it is
present, but was not resetting it to empty/anonymous when it was
not present. This patch corrects that, and adds a couple of test
cases to check that behaviour.

This fixes issue #86.
Bump version to 0.3.2 for bugfix.
