That's right.
Essentially, my patch fix 1. and 2. in the commit message of 2c8a7e5.
I am going to prepare one draft for the commit message based on Dima's 
message by Monday or Tuesday: i will drop mentions to the navigation 
commands.  Then i will show it here so that people in this thread can
give me comments/corrections to make the message clear for everyone.
