Fix command-line encoding processing.

String command-line options are converted to unicode using the input
encoding.

We use the fact that Python sets up the original sys.stdout to
determine the terminal encoding.

This should fix Anders Sneckenborg's issues with Swedish characters:

  C:\temp\slask4>be new "Svenska tecken åäö"
  Created bug with ID 6be/5c3

  C:\temp\slask4>
  C:\temp\slask4>
  C:\temp\slask4>be list
  ERROR:
  'ascii' codec can't decode byte 0xe5 in position 15: ordinal not in
  range(128)
  You should set a locale that supports unicode, e.g.
    export LANG=en_US.utf8
  See http://docs.python.org/library/locale.html for details
