     above the minimum size threshold is converted as a largefile. The

 shared also by largefiles b1, b2 in revision #2 and b in revision #5.
 
 Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
 summary" and "hg outgoing", even though files in outgoing revision #2
 and #5 refer it.
