Document bug in mandos-keygen which strips white space from passwords

Passwords, as read by mandos-keygen when given the --password or -p
options, are stripped of white space from the start and from the end
of the password.  This is because mandos-keygen is a shell script, and
the Bourne Shell "read" builtin does not seem to have a way to avoid
this.  Document this bug.

* manods-keygen.xml (OPTIONS): Document the white space-stripping
                               nature of the --password/-p option, and
                               also note in the description of
                               --passfile and -F that they avoid this
                               behavior.
  (BUGS): Again mention the problem with the --password and -p
          options, and suggest --passfile as a possible workaround.
