Actually, I wonder if this is just a bug.  The scm_error call in
scm_resolv_error passes the bad host name as a format argument, but
none of the error messages have format escapes.  So I suspect maybe
this call:

      scm_error (key, subr, errmsg, scm_cons (bad_value, SCM_EOL), SCM_EOL);

should actually look like this:

      scm_error (key, subr, errmsg, SCM_BOOL_F, scm_list_1 (bad_value));

so that we pass the bad hostname as one of the exception extra data
items rather than making it the first format string item.

Anyone have any counterarguments?
