both spam and deleted have the curious characteristic that you always want to hide the thread after either applying or removing that label. in all thread-index-views except for label-search-results-mode, when you mark a message as spam or deleted, you want it to disappear immediately; in LSRM, you only see deleted or spam emails, and when you undelete or unspam them you also want them to disappear immediately.
