Title:
  cryptsetup boot prompt doesn't handle passwords with backslashes

Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: cryptsetup

  This is reproducible in Hardy, I'm attempting to reproduce this in
  Lucid.

  Set your cryptsetup passphrase to a password with a backslash
  character.  For example, try the behavior with both "password\" and
  "pass\word".

  On boot when it asks for your passphrase, you must enter it with the
  backslash character escaped, e.g. "password\\" and "pass\\word".

  Note the very curious behavior when you use the password "password\".
  When you hit <enter> after the backslash, the password doesn't
  actually get entered, as if the newline is getting escaped.

  This seems to point to something maybe in its stty setup during the
  prompt?
