Userlist prints the total number of users at the top.

It seems that the total takes into consideration the user groups included in the list, but not the filter. (The number is the total number of users in the selected group, regardless of how many of them match the filter). I believe what should be shown there is the total number of users on the list.

Also, that total line always says: "(Site) has ## registered users". Since the whole purpose of having custom lists is to only display different subsets of users, saying that these are registered users is misleading. (Not really a bug, but it would be nice if the text was more generic, or - even better - if that text was configurable).

My site has 100 registered users. 35 of them are authors. I have a custom list that displays those authors who have a certain value in one of the profile fields - there are 25 of them. My list says:
(Site) has 35 registered users.
It then displays 25 users.

Note the number 35 is neither the number of actually registered user nor the number of users listed. Pretty confusing to the viewer.
