reassembly_queue.go:1

• The documentation is misleading. A single-chunk unfragmented message can have both beginningFragment=1 and endingFragment=1 simultaneously, as evidenced by the code at lines 248-250 that handles this case. The comment should clarify that for multi-fragment messages, the first has beginningFragment=1, endingFragment=0, the last has beginningFragment=0, endingFragment=1, and for single-chunk messages both flags are 1.
