calendar(1) regressions

[Jaakko Heinonen]

Hi,

Unfortunately r205821 [1] has caused several regressions to calendar(1).
Relevant PRs:

bin/157718
bin/162211
bin/168785
bin/170930

Some regressions were fixed in summer 2011 but they are still lacking
MFCs.

Is anyone aware of possible problems that reverting calendar(1) to
pre-r205821 version would cause? (Of course excluding the actual
calendar files.)
