Olaf is right with his suspection, but a fix is not as easy as it  
might seem as just specifying COLUMNS before starting Espresso is not  
enough (for some reasons). Setting env(COLUMNS) within tclline  
however fixes the problem. (And by the way, I like the new features...)

I had an initial look into tcl-readline a while ago because as  
frequent user of the interactive mode, I thought it would be a nice  
improvement. But I gave up, because I didn't find a handle to  
integrate it. If someone has an idea on it, I would greatly  
appreciate it. Looking into VMD might help since the console they use  
also supports readline. But please be aware, that their  
implementation is TK based and far from stable ...
