-This construct makes buffer BUFNAME empty before running BODY.
-It does not make the buffer current for BODY.
-Instead it binds `standard-output' to that buffer, so that output
-generated with `prin1' and similar functions in BODY goes into
-the buffer.
-
-At the end of BODY, this marks buffer BUFNAME unmodifed and displays
-it in a window, but does not select it. The normal way to do this is
-by calling `display-buffer', then running `temp-buffer-show-hook'.
-However, if `temp-buffer-show-function' is non-nil, it calls that
-function instead (and does not run `temp-buffer-show-hook'). The
-function gets one argument, the buffer to display.
-
-The return value of `with-output-to-temp-buffer' is the value of the
-last form in BODY. If BODY does not finish normally, the buffer
-BUFNAME is not displayed.
-
-This runs the hook `temp-buffer-setup-hook' before BODY,
-with the buffer BUFNAME temporarily current. It runs the hook
-`temp-buffer-show-hook' after displaying buffer BUFNAME, with that
-buffer temporarily current, and the window that was used to display it
-temporarily selected. But it doesn't run `temp-buffer-show-hook'
