Comment(by dsm):
Patch attached to allow support for infinity as upper bound and proof
option (with same semantics as next_prime's proof option: it's simply
passed through to next_prime).
First idea was to avoid casting to ZZ entirely, which would allow
primes(2, 100/3), but that can lead to some mysterious error messages.
Current approach simply special-cases infinity as an upper bound --
allowing -infinity as a lower bound isn't that useful, because unlike the
case of an infinite upper bound, that can be easily worked around from
outside the function, and so problems with the bounds are caught at first
iteration, which seems better.
