* init.cfg (trap_sigpipe_or_skip_): A new function refactored from... * tests/misc/printf-surprise.sh: ...here. * tests/misc/seq-epipe.sh. Likewise. * src/tail.c (die_pipe): Ensure we exit upon sending SIGPIPE. * tests/tail-2/pipe-f.sh: Ensure we exit even if SIGPIPE is ignored. * NEWS: Mention the bug fix.
