Re: recursive load case in openp

[Richard Stallman]

    I would argue that the `run-hooks' part of the function should be
    taken out.

That call is correct for the intended purpose of this function, which
is to support with-output-to-temp-buffer.

Anything which calls temp_output_buffer_setup and does not want to run
that hook should not call temp_output_buffer_setup.  coding.c
and fileio.c should not call it.

    Of course, in the mean time we should just create
    temp_buffer_setup and have temp_output_buffer_setup call it.

The actual code needed in coding.c was too small to be worth
such a subroutine.  I will fix fileio.c also.
