Great.  Maybe you could post more detail on this for others reading or
finding this thread later - what specific patch you needed.

BTW, you never mentioned why you need those cracked.

Why, you could as well run JtR on both hashes at once (one hash per
line or per file) unless you're focusing the attacks on these two hashes
differently.

Yes.  There are many different ways to do that, and which is best
depends on your specifics.  You could use the --min-length and
--max-length options, or/and you could use --mask (doc/MASK explains the
syntax of masks and gives some examples).

You don't need to do that.
