Bash's minimal configuration chose to keep output the same as historical
versions of sh. While the 7th edition sh omitted the SIG prefix, the
System V versions, including SVR4.2 (the most recent I have access to)
include it.

I assume that the Posix 1992 version made both kill -l and job control
part of the XSI portion of the standard. I don't have access to that
printed copy right now, so I can only speculate.
In any case, there's no reason to not fix this now.
