If I try to implement what you suggested, it will be *a*
*lot* more complicated then the current change.

I need to implement mapping of algorithm names in addition to mapping of
format names, because john-1.7.9-jumbo-5 used

SSE2i 12x
SSE2i 10x4x3
SSE2i 8x

Whereas the current git has

128/128 SSE2 intrinsics 10x4x3

And what if one file uses SSE2, the other SSE2i?
What kind of fuzzy logic should I implement to find the best match?

Furthermore, with -v, I would need to list both algorithm names (the one
from File1 and the one from File2) in addition to the format name in the
"Ratio:" output.

I think there needs a lot of thought put into the best possible
solution, and this will not be ready for the next jumbo.

For the next jumbo, I am still thinking about how to handle cases where
one file just contains
and the other file
Many salts:
Only one salt:

But I still don't have a good idea.
