I don't know what the normal behaviour is. I was expecting the remaining of
the line to be wiped out, but you must be right: the character 'c' is
already printed, the cursor moves back one position and go to the next
line, leaving the 'c' in place.
But what about this one:
> cat("abc\b\b\b")
> c
Here, I end up with the cursor being on the 'c', i.e. if I type something
it erase the 'c'.
It is strange that the 'c' appears _after_ the console prompt, isn't it?
