Commit Message

Eric Sandeen May 11, 2020, 7:20 p.m. UTC
A commit back in 2008 removed a "for" loop ahead of this code block, but
left the indented code block in place. Remove it for clarity and reflow
comments & lines as needed.

Signed-off-by: Eric Sandeen <sandeen@redhat.com>

(Probably easiest to review this by applying it and then doing 
git show -w $COMMIT to see only the non-whitespace differences)

Never mind, Darrick /just/ did this in his other series.  Weird.  I didn't
see it there! ;)

So ignore this patch.

Actually, I see that you fixed all the 80col stuff that I didn't.
Maybe I want this patch over yours after all. :P

Uh, so you reflowed all the comments and whatnot whereas I didn't, so:
