vi: code shrink print_literal()

Simplify the function print_literal() which is used to format a
string that may contain unprintable characters or control
characters.

- Unprintable characters were being displayed in normal text rather
  than the bold used for the rest of the message.  This doesn't seem
  particularly helpful and it upsets the calculation of the width
  of the message in show_status_line().  Use '?' rather than '.' for
  unprintable characters.

- Newlines in the string were displayed as both '^J' and '$', which
  is somewhat redundant.
