Deleting "last" message with $imp->sortdir==1

[Scott Wallace]

When in the message view mode (message.php3) and you delete a message AND the 
$imp->sortdir variable is set to 1 it deletes the message and then displays 
the "next" message.

Unforetunately, I read from "the bottom up".  Meaning I have my newer
messages towards the top, and read starting from the oldest messages.

I managed to hack the code to display the "prev" message after hitting
delete...

But when you reach message 1 ($array_index=0) and hit delete, then the 
$index=$sorted[$array_index] dies, like it should, because $array_index=-1.

I want to catch it before this stage and simply return you to the inbox view 
(just like when you delete the last message with $imp->sort_dir set to 0).

Make any sense?

Any ideas?
