Checking cp[1] before even knowing if cp[0] is the end of the string
(hence cp[1] is an out of bounds access) smells fishy.  If it were
something like ...

	if (cp[0] && strchr("@^", cp[0]) && cp[1] == '{')

... it may be a bit more palatable, perhaps?  At least writing it
this way we can easily scale when we find the third character we
need to special case, hopefully, but again, I do prefer if we can
find a solution that does not have such an intimate knowledge about
"@^", which I just failed to do here X-<.

Thanks.
