 When K = 1, any single share is sufficient to reconstruct the file.
 However, the servers-of-happiness code will still require that there are H
 servers with unique share numbers. It should not care about the share
 numbers.

 (We knew of examples with small K where the maximum matching definition of
 servers-of-happiness was conservative relative to the original definition,
 e.g. [ticket:778#comment:198]. However, for K > 1 it is more space-
 efficient to use the maximum matching definition. For K = 1 it is not.)
