Like strbuf_vinsertf(), it is a good idea to have "v" in the name of
a function that takes va_list, but fsck_vreport() would probably be
a better name here.  Arguably, the original report() is misnamed (as
a printf-like function that takes format string, it probably would
have wanted to be reportf() instead), but unless we are fixing that
at the same time, calling this fsck_vreportf() would probably be too
much.  Consistently misnaming it by omitting the final "f" would be
fine.

At this step it is still not clear if the previous step was really
needed; you have this "v" thing that is designed to be usable by
both reporting issues around objects and issues around refs, but we
will hopefully see why when we read later patches.

That is somewhat annoying reindentation.  What happened here?
