Re: Multiple runs of menu-bar-update-hook

[Richard Stallman]

    I guess that depends on your definition of a bug.  The hook isn't run at all
    when the buffer is shown in a single frame, but is run twice when the buffer
    is shown in more than one frame.  You say optato, I say bugato...  Or, at
    least, inconsistency.

    Does that mean you don't plan on optimising for this case?

I certainly don't intend to do it, and I would not want such changes
to be installed before the release.
