strings.  This isn't necessarily a bug, but it can be slightly inconvenient,
because atol() doesn't know how to parse hexadecimal or octal numbers and at
least one of the options of ffsinfo(8) would be easier to use if it did.

Changing atol() -> strtol() allows one to use hex masks for -l MASK, i.e.:
