Remove 'again' label, and don't loop there.
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
input port unbuffered & 'port-position'", "custom binary input port
unbuffered & 'read!' calls", "custom binary input port, unbuffered
then buffered", "custom binary input port, buffered then unbuffered"]:

New tests.

'setvbuf' works for different port types.
