No, this is wrong.  The two buffer implementations aren't quite the 
same, because the one inside src/xml.c sets virterror, whereas the one 
in qemud/buf.c doesn't:

-        virXMLError(NULL, VIR_ERR_NO_MEMORY, _("growing buffer"), size);

So there are some calls to the src/xml.c version which are doing stuff like:

    buf = virBufferNew(500);
    if (buf == NULL) return -1; // virBufferNew has set virterror

I would prefer my patch (see recent email) to go in instead of 8/20 and 
9/20, for this reason and also because my patch creates a separate lib/ 
subdir which I want to use for other library functions.

Rich.
