Subject: Markov: allow start and/or end to be specified in percent
I'd really love to get this into jumbo-6.
The code got a little bit uglier, but that can be fixed with a cleanup
patch later on, moving the new logic into a separate function.
This patch allows to specify start and/or end in Markov mode as percent
values.
(For now, I only allow integer values (0-99 for start, 0-100 for end,
where 0 is treated like 100.)
$ ./john --stdout --markov:200:1%:2%:12 |head -n 1
End: 2% converted to 5187128
Start: 1% converted to 2593564
MKV start (stats=$JOHN/stats, lvl=200 len=12 pwd=2593564)

$ ./john --stdout --markov:200:2%:4%:12 |head -n 1
End: 4% converted to 10374256
Start: 2% converted to 5187128
MKV start (stats=$JOHN/stats, lvl=200 len=12 pwd=5187128)

Allowing floating point values will probably have to be postponed until
after jumbo 6.
