[patch] Fix initilization problem in open_memstream

[Corinna Vinschen <vinschen at redhat dot com>]

Hi list,


I just applied the below patch.  I was testing an application which
neglected to print a string which had been created via open_memstream
functionality.  When debugging I found that the buffer was never flushed
in _sflush_r, because a member of the internal memstream structure
hadn't been initialized in internal_open_memstream_r.  The below
patch fixes the problem.

	* libc/stdio/open_memstream.c (internal_open_memstream_r): Initialize
	c->pos to 0.
