Then what about the `x' column specifier? (This is in groff 1.20.1.)
x,X An expanded column. After computing all column widths
without an x specifier, use the remaining line width for
this column. If there is more than one expanded column,
distribute the remaining horizontal space evenly among
the affected columns (this is a GNU extension). This
feature has the same effect as specifying a minimum
column width.
