Fixed a glitch when using using the keyboardselect and scrollback patches. (#48) 

Scrolling back and then entering keyboardselect's copy mode causes
glitched text to appear when moving the cursor. This is because the
keyboardselect patch is not aware of the scrollback history (term.hist),
so it takes the text from the last displayed screen (term.line).
