C source demonstrating bug

As reported on the mailing list:
http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-April/013328.html

The documentation for pa_stream_flush() reads, "This discards any audio in the buffer." To me, this implies that pa_stream_readable_size() should return 0 after a call to pa_stream_flush(). Tanu Kaskinen on the mailing list agrees, and asked me to report it here.

Attached is a program to demonstrate this failure. On my machine with PulseAudio 1.1:
$ gcc -pthread -lpulse -o test pulse_capture_flush.c
$ ./test
pulse is ready now!
format: 3
rate: 44100
channels: 2
stream is ready now!
pre-sleep avail: 0 bytes
post-cork avail: 349360 bytes
post-flush avail: 349360 bytes
