Log Message:
Update from version 1.61 to 1.70.

This despite some self-tests failing, but that's probably due
to deficiencies in the host system's locale implementation
(NetBSD/i386 4.0).

Pkgsrc changes:
 o Remove workarounds for 1.61a version

Upstream changes (could not find newer changes):

Changes for version 1.63 (Feb 10, 2009)
------------------------
  - Minor tweak to format_bytes test for German locales

Changes for version 1.62 (Feb 9, 2009)
------------------------
  - Change format_bytes to fully specify all formatting options, not
    rely on locale at all as it was causing too many CPAN tester errors.
