I had to add virBufferIndentEscapeString, since that could only take one 
%s in the format, but left virBufferAsprintf up to the user to exploit 
full formatting power.  But now that you mention it, yes, 
virBufferIndentAsprintf would make things easier to read.  I'll 
incorporate that into my v2.

Rather, I'll wait to push until I have a v2; Dan's suggestion for 
folding more indent smarts into virBuffer will also impact me.
