Changing font size or screen orientation should re-flow text

[verhovsky]

if you print a single long line of text

echo aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

that doesn't fit on a single line, then change the font size with Cmd+ using an external keyboard the text goes off the screen (and you can't even scroll to it) or with Cmd- it keeps the line length from when you ran the command when it could move the text back to a single line.
