Bug#571664: Date::Manip::DateCalc no longer properly handles addition of negative offsets

[Don Armstrong]

Package: libdate-manip-perl
Version: 6.05-1
Severity: normal

The 6.0 series of Date::Manip no longer properly supports the addition
of negative day deltas.

Compare:

$ dpkg -l libdate-manip-perl
ii  libdate-manip-perl      5.54-1                  a perl library for manipulating dates
$ perl -MDate::Manip -e 'print Date::Manip::DateCalc(q(20000131),q(+ -4 days));'; echo
2000012700:00:00
$ perl -MDate::Manip -e 'print Date::Manip::DateCalc(q(20000131),q(-4 days));'; echo
2000012700:00:00

with

$ dpkg -l libdate-manip-perl
ii  libdate-manip-perl                6.05-1                            module for manipulating dates
$ perl -MDate::Manip -e 'print Date::Manip::DateCalc(q(20000131),q( -4 days));'; echo
2000012700:00:00
$ perl -MDate::Manip -e 'print Date::Manip::DateCalc(q(20000131),q(+ -4 days));'; echo
$

This leads to an FTBFS in libhtml-calendarmonth-perl (and possibly other issues).
