What's the basis for believing that "we've already trained the users"?

With a little poking around the net, I did notice a couple examples
where people were reporting "info dll" results.  But in practice I
suspect that most GDB-using Windows developers are working on multiple
platforms, and they're likely to prefer commands that work everywhere.

On the other hand, "info dll" has been documented for a long time,
and is only one line of extra code - seems like more work to remove
than to leave it alone.

I do think we can dump the hook and just use add_info_alias.  I don't
remember exactly why the hook seemed necessary in the first place, but
the timing suggests I added it for gdbtk or MPW (or both. :-) ).
