def computeRendered(lastState: TermState): (Int, Str)
final def readChar(lastState: TermState, ups: Int, fullPrompt: Boolean): Option[String]
def redrawLine(buffer: Str, cursor: Int, ups: Int, rowLengths: IndexedSeq[Int], fullPrompt: Boolean, newlinePrompt: Boolean): Unit

Erases the previous line and re-draws it with the new buffer and cursor.

Relies on ups to know how "tall" the previous line was, to go up and erase that many rows in the console. Performs a lot of horrific math all over the place, incredibly prone to off-by-ones, in order to at the end of the day position the cursor in the right spot.
