[dovecot-cvs] dovecot/src/pop3 client.c,1.42,1.43

[cras at dovecot.org]

Update of /var/lib/cvs/dovecot/src/pop3
In directory talvi:/tmp/cvs-serv4344/pop3

Modified Files:
	client.c 
Log Message:
Changed ostream's flush callback to have return value which can tell if
there are more bytes to be sent even if there is none in output buffer
itself. Fixes FETCH commands which used o_stream_send_istream() getting
stuck.
