ascii.7: ffix: add vertical rule to separate the two columns

I regularly get mildly lost in this table (and, indeed, didn't realise
it had two columns the first few times I used it to look at something
from the left column) ‒ separating the two columns improves clarity,
and makes which soup of numbers belongs to which character
much more obvious

Other encodings don't need this as they don't use double-columnated
tables
