11030b7350 Delete whole utf8 character on backspace
...rather than just the last byte of the password buffer.

Demostrate the need for this by taking the following steps:
- Apply the patch below (before this commit).
- Set keyboard layout to one where utf8 characters longer than one byte
  can be obtained, for example åäö using Swedish layout
  (XKB_DEFAULT_LAYOUT=se).
- Type "åäö" then press backspace and observe that it takes two
  backspaces to delete each character fully, and therefore six
  backspaces to fully clear the password buffer.
