Under "Example using array and nested array formatting:"

writefln("My items are %(%s %).", [1,2,3]);

So "%( %)" is an array format specifier, with the stuff between 
the two as the element format. In the case of "%(%02X %)%*s  %s", 
that reads:

"%("    // Start array format specifier for arg 1.
"%02X " // Format each element as a 2 digit hex number followed 
by a space.
"%)"    // End array format specifier.
"%*s"   // Right justify arg 3 (""), using width specified by arg 
2.
"  %s"  // And print arg 4 using no special format.
