Then the doc string after my changes is exactly right.  I have no idea
what you see that's wrong with it.  You say some functions return menu
items and some return a list of menu items, and that's what the doc
string says.  You say that these values are displayed on the tab bar,
and that's what the doc string says.  So what exactly is wrong??
