# Confusing at first, but remember that it is *not* printfv's job to expand
# escape characters.  It is the job of the calling environment (C or shell)
# to perform any escape expansion.  Otherwise "$SNPRINTFV '\\%s' foo" would
# be expanded once by the environment, "\%s foo", and again by printfv
# yielding "%s".  Clearly this is wrong, we want to see "foo"!
