Would SV_NO be the same as \000, the ASCII null? I was poking around
last night and found that "\000" exhibits properties similar to the
return value from a failed s/// operation with regard to bitwise
operators and the printf facility.

On a side note, I wonder if poor Kevin Dowd is still following this
