churn: compute padding with unicode strings
Most UTF-8 aware terminals convert multibyte sequences into a single displayed
characters. Because the first column is padded by counting bytes, the second
column is not perfectly aligned in the presence of non ASCII characters.
Check whether size of generaldelta revlog is not bigger than its
regular equivalent. Test would fail if generaldelta was naive
implementation of parentdelta: third manifest revision would be fully
inserted due to big distance from its paren revision (zero).
