Ron,
	Go ahead and commit.  However, getting past this allows another
bug to show up.  I was reading 400K of input, and my program crashed.
Why?  encoded_read_buf->allocated_len was 1G, and
io_channel_fill_buffer() was calling g_string_set_size(encoded_read_buf,
2G).  Eek!  encoded_read_buf->len was only 15K at the time.  I suspect
it has something to do with the outbytes_left MAX() calls, but I haven't
sat down to look at it in detail yet.  I will probably get back to it
sometime this morning, but if you get there first I'm cool.  You can see
it if you change iotest.c to do "ls -l /usr/lib" instead of "ls
/usr/lib".
