That I knew already. I was just wondering out loud that if only two
arguments <*,*> were specified in the visualizer would it still work for a
type that included a custom allocator. I looked at how std::vector,
std::list, etc are specified and none of them include the extra parameter
for the allocator. So, I'm guessing that it would. Either that or the
default visualizers are incorrect.

As an aside, I've discovered that the $T1,$T2, etc. seem to go by the
"asterisks" and not by the template arguments. Given class_name<void**,*>
for example $T3 represents the second template argument. Go figure. At least
that was the case when I did the visualizer for
boost::void_ptr_iterator<void**,*> (used by ptr_array).

Now uploaded. The following containers and associated iterators are included
in this file:
        array
        ptr_array
        ptr_deque
        ptr_list
        ptr_map
        ptr_multimap
        ptr_set
        ptr_multiset
        ptr_vector

I followed your example and placed similar information at the top of the
text file. If it's not right or something's missing, you are free to modify
the file as necessary. Just let me know, so I can update my local copy to
match.
