Here's one more:

    CC       indent.o
  indent.c: In function 'scan_for_column':
  indent.c:69:10: warning: potential null pointer dereference 
[-Wnull-dereference]
     return 0;
            ^
  indent.c:69:10: warning: potential null pointer dereference 
[-Wnull-dereference]
  indent.c:69:10: warning: potential null pointer dereference 
[-Wnull-dereference]
  indent.c:69:10: warning: potential null pointer dereference 
[-Wnull-dereference]

I don't see how this could be anything but a GCC bug.  Yes,
buffer_display_table can return NULL, but every place that calls it
makes sure the result is non-NULL before dereferencing it.  Did I miss
something?
