Based on a report from Kim Hansen who wanted to send a KILL signal to the monitored command when `timeout` itself received a termination signal. Rather than changing such a signal into a KILL, we provide the more general mechanism of sending the KILL after the specified grace period. * src/timeout.c (cleanup): If a non zero kill delay is specified, (re)set the alarm to that delay, after which a KILL signal will be sent to the process group. (usage): Mention the new option. Separate the description of DURATION since it's now specified in 2 places. Clarify that the duration is an integer. (parse_duration): A new function refactored from main(), since this logic is now called for two parameters. (main): Parse the -k option. * doc/coreutils.texi (timeout invocation): Describe the new --kill-after option and use @display rather than @table to show the duration suffixes. Clarify that a duration of 0 disables the associated timeout. * tests/misc/timeout-parameters: Check invalid --kill-after. * tests/misc/timeout: Check a valid --kill-after works. * NEWS: Mention the new feature.
