Properly clear the last entered character
When enter is pressed, passwd[len] will be set to '\0'. Pressing backspace is supposed to remove the last entered character. But currently, the clearing has an off-by-one, as in setting passwd[len] to '\0' just like enter would do. You can also verify it by imagining len=1 and that it's impossible to clear passwd[0] by pressing backspace with the current code. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
