Don't shrink a column when it spans multiple columns
If a cell spans multiple columns, then the merged cells' starting
column's maximum width should never become smaller than what was
calculated from previous rows.
Otherwise, we'd distribute the space of the column that has a span
across all merged columns, resulting in unnecessary line breaks esp if
WrapAnywhere is enabled.
Add a test case.
