Tweaking htop display

htop is more flexible than top from procps. But recently I found a tiny inconvinience when htop display processes which use more than 10GB memory. Those processes use 6 characters in VIRT field, while normally it is 5 or less.

After small modification above, now htop behaves 'properly'.
