Well I personally think the best would to *always* take ^ literally,
whether quoted or not.

That would match the behaviour of bash and klibc sh, and also seems
more in the spirit of POSIX (which, while saying that an unquoted ^
produces undefined behaviour, also says that:
"( '!' ) shall replace the <circumflex> character ( '^' )""

... "replace", not complement.


Cheers,
