Subject: bleeding-jumbo shows DONE at any point when invoked with wordlist
 and without rules

During the contest I noticed strange thing: john (bleeding-jumbo)
shows DONE in status line at any point of cracking when invoked with
wordlist and without rules. There is no problem with rules. I tried to
repeat it on core and unstable-jumbo without any luck.

Hash below is bcrypt from the contest. Type of hash does not seem to
affect the behaviour:

$ cat t.in
NONE:$2a$12$xbo.K//p/qvakoyLhzp2tOMymZoJelyuxOa67HeUq5xtt.09J0Bim
$ cat t.pw
asfd1
asfd2
asfd3
asfd4
asfd5
asfd6
asfd7
asfd8
asfd9
asfd10
$ ./JohnTheRipper/run/john -w=t.pw t.in
Loaded 1 password hash (bcrypt [Blowfish 32/64 X2])
Press 'q' or Ctrl-C to abort, almost any other key for status
0g 0:00:00:00 DONE (2013-05-31 22:04) 0g/s 4.210p/s 4.210c/s 4.210C/s asfd5..asfd6

Story is the same with 1000 candidates in the wordlist:

$ ./JohnTheRipper/run/john -w=t.pw t.in
Loaded 1 password hash (bcrypt [Blowfish 32/64 X2])
Press 'q' or Ctrl-C to abort, almost any other key for status
