Subject: [PATCH] Fix ordinal() suffix for negative integers

value % 10 and value % 100 return non-negative results for negative
value in Python, so the suffix lookup in ordinal() always landed on
'th' for negative numbers (e.g. ordinal(-1) gave '-1th', ordinal(-21)
gave '-21th'). Compute the digit off abs(value) instead, while still
formatting the original signed value.
