Regression test for .Bl -column;

mandoc 1.9.14 still fails this one, patch being sent to kristaps@.

The groff .Bl -column spacing we are trying to follow is weird:
with less than 5 columns, groff puts 4 blanks between columns;
with exactly 5 columns, groff puts 3 blanks between columns;
with more than 5 columns, and also with more than 78 characters per line,
groff usually falls over and bites the dust - though the exact failures
look rather different in various cases, and a few cases even work...

No use trying to test anything for more than 5 columns, though.
