Always quote the right-hand side of expression when the == or != operator
is used, unless intended as a pattern.

Declare and initialize integer variables 'needsroot' and 'verbose'.
Don't use the fact that (( undefined_variable )) evaluates to 0.

Verify the argument to -k is a non-negative integer. Leading zeros
are simply stripped.
'declare -i keep' allowed the argument to -k to be any arithmetic
evaluation expression. The simple assignment 'keep=$OPTARG' triggers
arithmetic evaluation implicitly, which can either consume a huge amount
of resources with input such as '2**2**32' or immediately produce an error
on invalid input. Instead, we simply 'declare -- keep' and avoid all that.

This is superfluous as the ensuing for loop will exit immediately on the
same condition avoided by the if.

of options. Much credit goes to DJ Mills and Pat Brisbin for ideas
behind this script.
