  SVN rev 179567 on 2008-06-05 17:44:18Z by ed
  
  Fix faulty character to control-character conversion for CTRL().
  
  The CTRL() macro seems to perform character to control-character
  conversion (i.e. 'A' to 0x01) to lowercase characters. This is actually
  not valid. If we use lowercase characters, conversions such as
  CTRL('\\') and CTRL('?') will result to invalid conversions.
  
  Because we must still support old source code that uses CTRL() (bad!),
  we make CTRL() accept both forms. When the character is a lowercase
  character, we perform the old style conversion.
