libsmartcols: wrap does not work correctly in start/middle column

[ignatenkobrain]

But it works perfectly with last column:

Yes, we do not use \n ... the problem is that we're trying to print all the cell when we print one line, but it's multi-line cell. The best would be to print a table line in a loop until there is any multi-line column and all cell data are not printed yet.

The result should be something like:

AAA    BBB     CCC                            DDD
  1    hello   long multi-line                something
               cells are supported
  2       hi   short data                     another data    

... where CCC is WRAP column with multi-line cell on line 1. I'll try to implement it. It would be useful for more things.
