[krbdev.mit.edu #3030] Bug report: Kinit has no suport for addresses in credentials. Kinit -a is not enabled.

[Public Submitter via RT]

Some of the commentary in this bug doesn't make a lot of sense to me.  I
don't get the parts about referencing the local addresses variable; a
simpler change works fine for me in practice.

Anyway, attached is a slightly more complete patch that doesn't move the
addresses variable and that adds documentation strings.  I've tested
this patch and confirmed that it has the desired behavior.
