I tested this on the same CPE in another VRF and that works as expected;
the /24 prefix isn't announced when configuring the /21 network
statement. A /21 Null0 prefix is announced as expected.

So it seems to be a bug. It's a C3560 running 12.2(35)SE5 IP Services.
I'll start searching the Bug Toolkit and Release Notes...
