[podwiki] Table syntax fix

[David A. B. <Br...@ac...>]

Tom,

I've checked in the fix you asked me to work on for tables. The =rowback
directive is still accepted, but it is not required. You can now format a
table like this:

=table

=row

=cell

Row 1

=cell

R1, C2

=rowback

=row

=cell

Row 2

=cell

R2, C2

=row

=cell

Row 3

=cell

R3, C3

=tableback


Note that in row 1, I used the =rowback directive, just for illustrative
purposes; it isn't required. The other rows show separation by just the =row
directive.

The change was mostly in Node.pm, where I changed the _make_rows function to
be more like _make_cell, with successive rows siblings of each other, and
cells are children of the rows. There was also a corresponding change in
Runner.pm so that walk_row knew to go through the sibling nodes.

Take a look when you have time and let me know what you think. By the way, I
was a bit over-zealous in cleaning out old email the other day and deleted the
last message you sent me. I believe you asked me to take a look at something
else, besides the table fix, too, but can't remember what it was. Could you
remind me?

Thanks.
