[1] Sending backspace to the terminal doesn’t do what you would expect on the left edge. This also impacts when you cursor-up/down through the CLI history if those lines are longer than the terminal width.

When VPP cli configuring multi line content, then continuously input '\b', or press' backspace '/' backspace 'continuously, the CLI cursor can only go back to the left of the line and cannot return to the last line. How can this problem be solved?

Example：

first:

VPP# aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

aaaaaaa

then input 'backspace' , can only be deleted last seven 'a'

VPP# aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
