 the cursor is enabled or not. When it's disabled, the cursor is drawn
 as a space character.
 
+Also, the cputc() here no longer requires \r\n to move the cursor

+The cputcxy() routine has been deleted, since taipan doesn't use it.

 Benefits of doing this:
 
 - Faster and smoother screen updates
-- Slightly smaller code (20-30 bytes)
+- Slightly smaller code (100-odd bytes)
 - No more "cursor ghosts" at timed prompts
 - No need for a hide_cursor() function
+- print_msg() from textdecomp.s is simplified, it no longer has
+  to print a carriage return every time it sees a newline in a
+  compressed message.
+- In taipan.c, cputs("foo\r\n") no longer requires the \r, saves
+  one byte per string.
 
 Disadvantage: Have to draw the cursor myself when needed. It turns out
 that only agetc() needs to do this, so not a big deal. Also had to
