% 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!
