Details:

Consider this example:

main()
{
  char *x[2] ={
    "top left                                           top right",
    "bottom left                                        bottom right"
  };
}

Set break on closing } and run.  Then graph display x, and graph display
x[0].

If "set print repeats" is 10, the the display of x will contain 6 elements:

"top left" | ' ' <43x> | "top right" | "bottom left" | ' ' <40x> | "bottom
right"

and the display of x[0] will just show "top left".

This occurs because the output of "print x" contains commas which are
interpreted by DDD as field separators:

(gdb) print x
$2 =   {0x400550 "top left", ' ' <repeats 43 times>, "top right",
  0x400590 "bottom left", ' ' <repeats 40 times>, "bottom right"}

I can work around this by setting "set print repeats" to a large value. 
Probably DDD should temporarily override the user-set value of this parameter
when capturing data for displays.
