Bug fixes:
----------
* fork.cc (frok::parent): Call CreateProcessW with command line set to the parent command line. Change comment to explain why.

- getgrouplist now always creates a group list, even if it's empty.
Fixes: http://cygwin.com/ml/cygwin/2013-05/msg00157.html
- In fork, call CreateProcessW with the same command line as the parent
process. This seems to make sure the stack is created in the same
memory location as in the parent.
