Hello,

the current version of killall(1) does not allow sending signals to processes
attached to a pts(4) e.g /dev/pts/4 and to do so results in an error messages
like the one below. 

#killall -t pts/4
killall: stat(/dev/ttypts/4): No such file or directory


The provided patch would enable the ability to do that.

Best regards

Daniel Dowse
