-The buffer is cleared out initially, and marked as unmodified when done.
-All output done by BODY is inserted in that buffer by default.
-The buffer is displayed in another window, but not selected.
-The value of the last form in BODY is returned.
-If BODY does not finish normally, the buffer BUFNAME is not displayed.
-
-The hook `temp-buffer-setup-hook' is run before BODY,
-with the buffer BUFNAME temporarily current.
-The hook `temp-buffer-show-hook' is run after the buffer is displayed,
-with the buffer temporarily current, and the window that was used
-to display it temporarily selected.
-
-If variable `temp-buffer-show-function' is non-nil, call it at the end
-to get the buffer displayed instead of just displaying the non-selected
-buffer and calling the hook. It gets one argument, the buffer to display.
+
+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'
+if it uses `temp-buffer-show-function'.
