>Description:
The 'fold' utility reads past the end of a buffer if arguments are
incorrectly specified. If you pass an argument to '-b' that happens
to be in the character set "0123456789", line 101 reads past the
end of argv[optind] and causes a segmentation fault.
>How-To-Repeat:
Simply run 'fold -b1'
>Fix:
I don't really see what the author is intending to do in that case
statement where it breaks.
