Word wrapping bug partially corrected

Bug on the word wrapping routine when the word's end is exactly one
character past the end of the line is corrected; text still won't display
correctly if the current word exactly matches the end of the line.
Word wrapping bug corrected

There was a bug where the text wouldn't be correctly displayed if the last
character in the last word of a line was at the last text column.
Also corrected a bug that happened if there was a line break exactly at
the last text column.
