Because I have no idea how edebug-defun is working. For me it never  
worked in the sense of seeing something like in GUD/Gdb. And the  
edebug info node does not seem helpful for me. Once again I stopped  
reading theoretical stuff that I can't easily follow and that might  
be meant for a different situation, one in which a developer is  
debugging some own function.

And doing it the other way round, as tried today twice or three times  
before, i.e. first loading auctex.el and preview-latex.el and then  
invoking edebug-defun, I see no change. Or, to be honest, I see now  
in *scratch* buffer a dark triangle in the left fringe, that "links"  
to the *Messages* buffer, on the line where preview-latex.el was  
loaded. And of course *Messages* tells something different:

No. I wouldn't need to complain when I would receive some real help.  
I don't see that I could learn to debug other folks' functions with  
edebug-defun when I have no idea how to use this, successfully or  
not. Some folks are helpful and man enough to give this help. Of  
course I can be completely wrong assuming debugging with edebug-defun  
is not as simple as looking tv.

Good point.
