wp_list_cats() always shows children categories

[skippy]

Documentation for wp_list_cats() in the wiki states:

children - boolean - TRUE or FALSE;
Whether you want to hide or show the
children of the main categories
(top categories only)

When set to "children=FALSE", the only appearant difference is that children categories are output, they're just not nested in the display.

As it stands, 'children' determines whether the child categories are displayed hierarchically or not. Perhaps it would be best to rename 'children' to 'hierarchical' and update the documentation.

Should there be a 'children' option? Is it desirable to be able to display only the top-level categories? Seems to me somebody will want to do this at some point.

Displaying only top-level categories is _exactly_ what I wanted to do. Then I'll include logic to see if the reader is looking at a specific category. If they are, then that categories' children categories should be displayed nested underneath it.

[JasonV]

children=0 will now stop categories below the top level from being displayed
hierarchical=0 will stop categories from being displayed hierarchically

By default, children will be displayed and the display is hierarchical.

Sounds like a good fix. Thanks very much!
