combinator attack : empty dic

[/milzo]

When trying to append $- to first dictionary, hashcat claims it's empty, prepend ^ working fine.

eg.

Code:

./oclHashcat-plus64.bin -a 1 -j $- -m 0 -o /outfile.txt /infile.txt /rockyou.dic /dic2.dic --remove

oclHashcat-plus v0.12 by atom starting...

Generated dictionary stats for /dic2.dic: 59992 bytes, 6210 words, 0 keyspace                    
/dic2.dic: empty file

either a bug or user error, what you think?
