Comment:

 Thanks for the patches. It looks like the reason for the `if ( true ===
 $hierarchical )` block is to ensure that excluding a category also
 excludes its descendants. So wiping out `$r['exclude']` altogether doesn't
 seem like an acceptable strategy. We want to allow for the possibility
 that someone would pass `exclude` *as well as* `exclude_tree`, and have
 both of them (and their descendants) excluded from results.
