For shell trap purposes, "1 2 3 13 15" is the same as "HUP INT QUIT PIPE TERM" in AIX, FreeBSD, Hurd, illumos, Linux, macOS, NetBSD, OpenBSD and Solaris. However, in Haiku SIGPIPE is 7 and 13 is SIGTSTP. Address all warnings from shellcheck 0.9.0: mkdep:66:11: note: Double quote to prevent globbing and word splitting.
