Hmm. I guess I was confusing this with the --with-krb-srvnam configure
directive, and expecting that it ought to convert that from a
frozen-at-configure value into a run-time-configuration variable.
What is the relationship of these two values, anyway?

The documentation additions are pretty poor in both proposed patches;
they do nothing to clear up any confusion.
