[Groff] Meta-tbl: last know bug fixed

[baruchel]

Brest, le dimanche 6 août

Hi boys,

there was still a known bug (bottom line of a doublebox). It's now fixed

I would be very happy if you try that tool, and tell me the other bugs.
Anyway, I think this macro can now be really and fully used in many cases.
Let me know if you like it.
Last time I forgot to tell the name of the col-filling command.
The three command are:
.m4tfc x y n (fill cell x,y with darkness of n)
.m4tlf y n   (fill line y with darkness of n)
.m4tcf x n   (fill column x with darkness of n)

The main usage has been already told in prevouis messages.
