vt: tag cells that were form-feed:ed, to allow correct text reflow

Browse source 
To handle text reflow correctly when a line has a printable character
in the last column, but was still line breaked, we need to track the
fact that the slave inserted a line break here.

Otherwise, when the window width is increased, we'll end up pulling up
the next line, when we really should have inserted a line break.
