    Add a full version of CP437, including 01-1F and 7F.
    
    The unicode.org translation table for CP437 doesn't include the
    printable glyphs that the full character set puts in these positions.
    But sometimes you want them anyway, so here's a version of CP437 that
    uses them.

    convcs: add a --passthrough option for control characters.
    
    If you're converting a text file from a character set such as the new
    CP437full, or indeed the older ISO-8859-1-X11, then you might need to
    strike some kind of a balance between passing through some C0 byte
    values as control characters (newline in particular might be hard to
    do without), and translating others as specified by the charset.
    
    Rather than try to make a huge collection of intermediate versions of
    CP437 guessing at which subsets of control characters anyone might
    need, I've implemented this as a command-line option in the convcs
    tool. So now you can say, for example,
    
      convcs --passthrough=10,13 cp437full utf-8
    
    and get _most_ control characters converted into the Unicode
    representations of their CP437 glyphs, but pass CR and LF through
    unchanged.
