Submission from: (NULL) (144.203.11.223)

Can we add support for const char** as we have support for void* and char*?
This would be consistent with the 'p' and 's' type to to_a when given a 
null ptr terminated list of strings allocated from a buffer. The problem is 
if I use 's' it will segv when xfree is called. I can use 'p', but it isn't
as pretty. ;-)

Thanks,
Will
