This email is just for your attention. I'm relatively new to work in a

the comments.

Yes, trimming to just relevant context is a must for any high-volume patch list. Also, separate your replies from the quoted material by blank lines, so it stands out better (visually, I find it easier to spot replies that appear in isolation, by scanning just the left column; not to mention that some mailers corrupt long lines on quoted replies where a long single-line paragraph in the original turns into a wrapped multi-line text with the first line quoted but subsequent lines unquoted; adding whitespace before your reply makes it obvious that you made the comment, rather than your mailer reformatting things).

+ if (virBufferGetIndent(buf, false) != 1 ||

+ virBufferError(buf)) {
+ TEST_ERROR("Wrong indentation");
+ ret = -1;

So now buf->indent is 1. Go to the next step, the indent is given -2
again, see what will happen.
if virBufferAdjustIndent failed to check the indent overflow, the
buf->indent will be -1,too, so it may avoid the check
(virBufferGetIndent(buf, false) != -1) and (virBufferGetIndent(buf,
true) != -1).
+ virBufferAdjustIndent(buf, -2);
So I think -3 may be better.

Good idea; I've folded that into my patch.
