Wanted to user virBufferPtr, but I realized that I need to remove
the last comma from the string and coudn't find an easy way to
do that. Hence resorted to this method. But I think I can still
achive this by not appending a comma to the next part of the agrument
(,mems). Let me see if I can do this cleanly in the next post.
Yeah, it might make sense to first add a helper function to
util/buf.[ch] that allows one to truncate previously appended bytes,
since sometimes it is easier logic to say always emit a trailing comma
then trim than it is to say emit a leading comma if I'm not first.
Nothing wrong with adding helper functions to make life easier, if
virBuffer doesn't already meet your needs.
