Two places in the code don't agree what happens with virtual text that
is placed somewhere inside the line. When drawing the text it is
truncated at the window edge, when computing the cursor position it is
not truncated.
I actually do not see a good reason why this text would be truncated at
the window edge. It is inserted at a certain position in the text,
there is no relation whether this is close to the window edge or not.
Let me not truncated the text, see if any tests fail. If that seems to
work we'll have to see if some users depended on the truncation.
