cplus-dem.c tiny patch

[Andrew Haley]

If a process sends an address followed by a newline to c++filt and
then waits for a symbol string terminated by a newline it may wait
forever; c++filt doesn't flush its output buffer before going back to
waiting for input.

	* cplus-dem.c (main): fflush() after emitting last char before
	waiting for input.
