Fixed the marginpar-handing stuff to put function names into the margin.

Names begining with krb5_ now have that prefix stripped before it's
put into the margin.

+%  This function fixes up the function name to be displayed in the
+%  margin so that the krb5_, if any, is stripped.
+%
+%  Note: this is a hack; what's really happening is that name beginning with
+%	krb5 will have its first five characters stripped from it.
+%	This means that 'Krb5abc' will get rewritten to be 'bc'.
+%	Unfortunately, we can't do better because of the underscore
+%	hacks that are going on elsewhere.
+%
+%  WARNING: This is ugly; don't look at it too soon after lunch!
