RE: Add hook to end of `custom-create-buffer-internal'

[Drew Adams]

        Please a new hook, say, `custom-buffer-create-hook', and
        run it at the
        end of `custom-create-buffer-internal'.

    Suppose we move the call to custom-mode to the end of
    custom-buffer-create-internal.  Would custom-mode-hook then serve
    this purpose?

That would be OK as far I'm concerned.

         This is for things to be done
        _after_ the buffer has been filled with its text. An example: a
        function to fit a one-window frame to the buffer contents.

    It seems that special-display is the right way to do this job.
    Can you do the job that way?

I'm not sure what you mean. What is "special-display"? Are you thinking of a
special-display buffer somehow? Remember that a *Customize...* buffer might
or might not be a special-display buffer. I'm really not clear what you're
suggesting here, sorry.
