Hi,

While trying to chase down the problem regarding the stacktraces,
I have also found some minor problems in the code.

Would appreciate any review or feedback regarding them.

Thanks
Farhan

ChangeLog
---------
v1 -> v2
   - Update docs for csch/hsch since we can support those
     instructions now (patch 5)
   - Fix the memory leak where we fail to free a ccwchain (patch 2)
   - Add fixes tag where appropriate.
   - Fix comment instead of the order when setting orb.cmd.c64 (patch 1)
