+A COLUMN spec consists of a column name and an optional column width; the

+\`+0'.
+  NAME=WIDTH   Exact width: truncate the contents to fit if necessary.
+  NAME:WIDTH   Minimum width: spill into the next column (breaking the

+  NAME+WIDTH   Minimum width: if a value won't fit then make the entire
