Block the deletion of prompt string

[helio-frota]

Now we have a static PS1 like this:

[mterm@localhost ~]$

We need to block the deletion of PS1 , i mean the caret cannot move with backspace or other key to the left after '$'.

btw, now we have a dynamic user + hostname PS1 👍

[helio-frota]

now we have to block the backspace until the PS1 length to close this issue !
