Subject: 23.1; shell-command overwrites whole buffer
Date: Mon,  9 Nov 2009 11:14:14 +0000 (UTC)

Starting emacs 23.1.1 with the '-q' argument and typing:

  M-: (shell-command "date" (get-buffer "*scratch*"))

results in the prior contents of the *scratch* buffer being
overwritten.  This seems to contradict the last sentence in the
following paragraph of the docstring for shell-command:

    The optional second argument output-buffer, if non-nil, says to
    put the output in some other buffer.  If output-buffer is a buffer
    or buffer name, put the output there.  If output-buffer is not a
    buffer and not nil, insert output in current buffer.  (This cannot
    be done asynchronously.)  In either case, the output is inserted
    after point (leaving mark after it).
