am/apply: warn if we end up reading patches from terminal
In an interactive session, "git am" without arguments, or even worse, "git am --whitespace file", waits silently for the user to feed the patches from the standard input (presumably by typing or copy-pasting). Give a feedback message to the user when this happens, as it is unlikely that the user meant to do so. Signed-off-by: Junio C Hamano <gitster@pobox.com>
