Aria Engine negative Number Index handling

First, I didn't tested the other Versions which may be affected too. But 10.0.4 defenitely has this bug.

We may have a normal table with the aria engine like

CREATE TABLE IF NOT EXISTS `sometable` (

  `id` int(11) NOT NULL DEFAULT '0',

  `somechars` varchar(50) NOT NULL DEFAULT '',

  PRIMARY KEY (`id`)

) ENGINE=Aria DEFAULT CHARSET=utf8 PAGE_CHECKSUM=1;

The problem is, we can insert negative Numbers in the primary Key but it is not possible to edit, delete or search for them anymore. Unless u search for !=0 or something, but =-1 wouldn't work.

And now: Thanks for your awesome work and keep going doing fantastic stuff!
