Fix missing ellipsis when just one character is truncated

The "moreChars" test in StaticLayout's generate method would evaluate to
false when the last character in a word caused the break. This in turn
suppressed the ellipsis in this case. The proposed fix is always to set
moreChars true in the code path where the line is broken because more
text wouldn't fit.
