Subject: Avoid messing up the display when too many letters are guessed at
 once.

The field to put them in was made 26 characters wide... but includes
the string "Guessed: ". So if you get to 17 it wraps to the next line
and clreol()'s it. Instead, when reaching this point step on the
"Guessed:" string instead.
