vpatch: allow a word to have text before the newline.

Previously we don't print out ends_line() words at all.
But soon a word might have some content plus a newline at
the end.
So restructure the display to print non-newline characters
from any word.
Note that we cannot have characters *after* a newline.
Doing that would break too much of wiggle's formating
assumptions.
