An earlier commit cbd64af added a check that prevents "git-am" to run without its standard input connected to a terminal while resuming operation. This was to catch a user error to try feeding a new patch from its standard input while recovery. The assumption of the check was that it is an indication that a new patch is being fed if the standard input is not connected to a terminal. It is however not quite correct (the standard input can be /dev/null if the user knows the operation does not need any input, for example). This broke t3403 when the test was run with its standard input connected to /dev/null. When git-am is given an explicit command such as --skip, there is no reason to insist that the standard input is a terminal; we are not going to read a new patch anyway. Credit goes to Gerrit Pape for noticing and reporting the problem with t3403-rebase-skip test. Signed-off-by: Junio C Hamano <junkio@cox.net>
