@Tab work in progress

[Jeff Kingston]

To stimulate your interest, here is some -p output from my
private current version of Lout:                     
 
     A                B                 C
 
     This is quite  a long paragraph    C
     of text that will certainly re-
     quire breaking, so  should pro-
     duce interesting results

I'm still working in raw Lout, not @Tab yet; the input that
produced this was
 
@Page {
     A            |4s  B             |4s  C
/1v
     @Span @Thing |    @HSpan        |    C
/1v
     A            |    @Span @Thing  |    @HSpan
/1v
     @Thing       |    @Thing        |     @Thing
}
 
where @Page is just widths and margins, and @Thing is the
paragraph you can see.  Keep those suggestions for @Tab
rolling in.  Yes, there will be vertical spanning, and
combined horizontal and vertical spanning.
