Then I don't understand why NEWS says

  *** The tab bar is frame-local when 'tab-bar-show' is a number.
  You can show/hide the tab bar independently for each frame, according
  to the value of 'tab-bar-show'.

If you say that frame-local tab bar _overrides_ tab-bar-show, then how
come the value of tab-bar-show is described here as _causing_ the tab
bar to be frame-local?
