On second thought, after some IRC discussions with others, I'm planning on:

1. push your patch as-is for 0.9.1 (it's minimal, which is good since
we're post-freeze)
2. after 0.9.1, revert your patch, and replace it with:
3. global rename of virBufferVSprintf -> virBufferAsprintf (to match the
existing virAsprintf name)
4. add virBufferVasprintf (to match the existing virVasprintf name)
5. fix virsh to use virBuffer, including the new virBufferVasprintf
