This is good stuff (for what it is).  I feel that the patch is misnamed,
though.  By "large files", some people mean files larger than 2 GB on
32-bit systems, which would be another feature (for wordlists).  Maybe
"large-passwd-files" would be it, although it's really "passwords per
salt" that matter here.

Also, let me use this opportunity to advertise these guidelines on how
to make & submit patches for JtR:
