* src/operand2sig.c (operand2sig): Add a detailed comment explaining why we validate even very large shell exit status values. * tests/misc/kill.sh: Add a test case for the ksh scheme. Simplify the INVALID signal number determination which also avoids a false failure on systems like FreeBSD 10 with incomplete signal list (caused by inaccurate NSIG).
