	* src/lib/krb5/krb/gc_frm_kdc.c: Also do style cleanup.
	(krb5_get_cred_from_kdc_opt): If server principal was rewritten,
	fall back unless it was rewritten to a TGS principal.  This fixes
	a bug when a MS AD rewrites the service principal into a
	single-component NETBIOS-style name. If we get a referral back to
	the immediately preceding realm, fall back to non-referral
	handling.  This fixes the changepw failure.  To prevent memory
	leaks, when falling back to non-referral handling, free any tgts
	previously obtained by the initial non-referral do_traversal()
	call.
