draw.c:30: error: CHECKERS_DEAD_CODE
  Node not visited: 20
  28.   static inline char get_char(char c)
  29.   {
  30. >     if (c > 31 && c < 127)
  31.           return c;
  32.       else
  33.

Original code here: https://github.com/dwbuiten/bxd/blob/master/draw.c#L28-34

This makes it go away / happy, but I cannot figure out WHY:

-    if (c > 31 && c < 127)
-        return c;
-    else
-        return '.';
+    return (c > 31 && c < 127) ? c : '.';

Removing the 'else' line 'fixes' it too.
