"User Updated" text sticks after first successful update in admin page

[redsweater]

If you make a single successful change in the user profile editor in wp-admin, it tacks a "updated=true" parameter onto the GET URL, which sticks even as you continue to make possibly ineffective changes.

1. Go to a user's edit page in wp-admin.
2. Make a successful change such as changing a first name.
3. Observe the "User updated." div near the top.
4. Make an unsuccessful change such as a failed password change by entering different values in each field.

Result: the "User updated" div continues to appear in spite of the errors.

Whenever a submission causes zero changes to occur on the user's profile, any existing "User updated" div should be hidden.

(This is in trunk r10492.)

this is an edge case, so punting. it would need to be checked/done in other admin screens as well.

• That change passes a clean url to the post, so teh updated arg doesnt follow through.

Tested on

• Own profile page
• Another users edit page

• Better patch using admin_url() instead
