[Snort-sigs] PCRE for SS#'s

Someone on the snort-users list asked how to detect SS numbers in a
snort rule, I put the one I wrote out there and was quickly reminded how
lacking my PCRE kung foo is.  With the input of the reformed rules nazi
and a few others I got some input that helped me re-write the PCRE for
it and I wanted to run it past this list and put it out for anyone that
it might help.

/\b[0-9]{3}-[0-9]{2}-[0-9]{4}\b/

Without the \b I was getting too many false positives, mainly form web
cookies.  Let me know what you think, and thanks for the help and any
suggestions.
