I'm not sure I agree. It depends on how big a chunk you consider for
consistency: a function, a file, or the whole project.

fsck_tree() was already inconsistent, so this is making that function
totally consistent. Since that was the function I was working in, that
seemed like the limit of "while I'm here", and I'd prefer to keep it
there for the series.

I certainly don't mind extra clean up on top, though.

As far as preferring the long lines, I don't mind lines a _little_ long,
but some of these are 120+ characters. They wrap awkwardly even on my
extra-wide terminals. ;) I guess we can have a discussion on whether
long lines are OK, but it should probably center on what we put into
CodingGuidelines, and not these particular lines.

I think it gets tricky, as not all of the strings have the same number
and type of format specifiers (most don't have any, but verify_headers()
for example uses %ld).
