May be it is a good idea to look how other formats where converted from
a simple implementation into a tuned implementation.
Since we don't have a tutorial or a how-to guide for this, I think the
best way to figure out what needs to be done is to look at specific
commits of a format that has recently been added.
I think the best candidate is the sapH format, since it has been added
recently, so that there aren't too many commits which are unrelated to
tuning the format.

$ git log sapH_fmt_plug.c

just shows 16 commits in bleeding jumbo.

Those commits related to JtR refactoring are quite easy to distinguish
from commits that actually tune the format.
