+    Fix commands that don’t need to have a non-empty mailbox to be valid
+    
+    Some commands act on the whole mailbox (tag-pattern, delete-pattern,
+    search), and even though they don’t do anything when the mailbox is
+    empty, there is no reason to fail when it happens. This commit removes
+    the check that the mailbox is non-empty before doing said actions.
