This matches the constants from <signal.h> with 'SIG' removed, which POSIX requires kill and trap to accept and 'kill -l' to write. 'kill -l', 'trap', 'trap -l' output is now upper case. In Turkish locales, signal names with an upper case 'I' are now accepted, while signal names with a lower case 'i' are no longer accepted, and the output of 'killall -l' now contains proper capital 'I' without dot instead of a dotted capital 'I'.
