tbl(1): Document x col modifier as DWB extension.
...and a late one, at that.
System V troffs (all descended from DWB 2.0 troff, as I understand it)
don't have it. Plan 9 troff doesn't either, despite having repeated
episodes of cross-pollination with DWB 3.x. Heirloom Doctools
implemented it in 2015, claiming falsely that it was a GNU extension.
