That's interesting, since the fieldwidth (and precision) end up getting
set to 0 if they overflow INT_MAX, at least on my machine, and the result
is more or less instantaneous.  I agree that bash should do the same
thing in printstr when presented with an overflowing field width that it
does when using getint().  I will look at making that change.
