It's the standard:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/kill.html#tag_20_64

"Historical versions of kill have not written the SIG prefix for the -l
option and have not recognized the SIG prefix on signal_names."

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_28

"Implementations may also accept the names with the SIG prefix; no known
historical shell does so."
