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.
