I did some short test from fresh git unstable branch (commit fc8c9fd7). Seems
new incremental mode works fine.
I generated new charset:
$ ./john --pot=../pots/john.pot --make-charset=../chrs/test.chr
Loaded 240928 plaintexts
Remaining 240927 plaintexts
Generating charsets........................ DONE
Generating cracking order..-------+-----------------+----+--------------------------+-- Stable order (62 recalculations)
Successfully wrote charset file: ../chrs/test.chr (159 characters)
For fast test i set small length and CharCount:
[Incremental:test]
File = $JOHN/../chrs/test.chr
MinLen = 7
MaxLen = 8
CharCount = 12
Non-interrupted session:
$ ./john --format=raw-md5 --pot=w-o_interrupt.pot --incremental=test --encoding=cp1251 ../hashes/md5

With interrupt it takes 2 seconds more, may be due machine is under other desktop load.
Cracks the same:
$ cmp -u w-o_interrupt.pot w_interrupt.pot
$
Should I do test more long sessions (with more big MaxLen and CharCount)?
Also, progress indicator is always shows 0:00%, it is correct?
