I've changed the logic so that the pretty-printer tries to get the
__tostring metafield regardless for value type so this should now work
as expected for all values supporting a metatable and having a
__tostring method.  Your simple example seems to work for me now:

>  ffi=require"ffi" t=ffi.metatype("struct{int a;}",{__tostring=function(x) return "custom tostring " .. x.a end})
>  t
ctype<struct 95>
>  {t, t(2)}
{ ctype<struct 95>, custom tostring 2,  }
>

I'm attaching the modified sources so that they can be used and tested
by anyone interested.  If I don't get any complaints after a while
I'll make a new release (unless I forget it).
