Subject: change usage of pp in Test::Unit assertions

Hi all.

I have some Test::Unit testcases that deal with Date and DateTime. If,
for whatever reason, I have a failing assert_equal on either Date or
DateTime, the resulting message is quite difficult to read: the reason
obviously is that pp dumps the content of the object, it doesn't rely
on to_s or other more readable ways.

Is there any way to change this behaviour and make assert_equal print
Date.to_s and DateTime.to_s when the comparison fail?

TIA
