Re: matlab-history-beginning-search-backward

[Guido van Steen <gvsteen@xxxxxxxxx>]

Dear Peter, 

I am impressed by the code. It works well - apart from the 
cursor stuff. I tried to understand it, but I failed. 

I have two questions: 

* Which part of the code makes sure that the commands retrieved 
from history are "shown" on the command line? 

* Why does the cursor position matter, and how can one make sure 
that the cursor moves to the right position before the widget is 
invoked? 

Best wishes, 

Guido
