OK, so parse-options messes up if the user specifies a count that does
not fit in 'int'? Although that's a separate bug, let's not make things
worse here; let's make the new count an 'int'.
In the long run parse-options should be changed to use strtoimax instead
of strtol, and the corresponding integers should be changed to intmax_t,
and the proper thing should be done if the string value does not fit
into intmax_t. But this longer-run fix affects all integer-valued
options, not just this one.

Such comparisons cannot misfire if both values are nonnegative, and that
can easily be arranged here.
