==================================================================

In first chunk of patch, it removes very bad case, that if len (of text
drawable) is less than 3 characters, it will cause underrun of text
which is draw via X call:

for(i = len; i >= MAX(0, len - 3); buf[i--] = '.');

because len was unsigned, then if len < 3, len - 3 will be very big
number (because it's unsigned).

Second chunk is only detail, to avoid unused variable in case XINERAMA
is not enabled in compile time.
