Thank you for the feedback!

When my current mundane duties (cooking, studying, cleaning, grocery, 
jogging, take care of my cat and cactus, etc) offer me a break,
I will prepare a new patch (not sure when I will find the time, 
hopefully soon):

* It will recycle (require) `comint.el', i.e., it will use 
`comint-password-prompt-regexp'.

* It will use the hook strategy until someone comes with something 
smarter.
