The inner brace removal is okay, but I tend to use {} on anything that
occupies more than one line (even if only one statement), particularly
if more than one of the nested lines have the same indentation (as is
the case with the split-line if). That means I think the outer braces
should stay.
Yes, good point. Also, looking at that section of HACKING again, it
says the braces can be omitted "only when that
body occupies a single line".

This one's borderline - it's more than one line, but at different
indentation, so it's not as visually difficult to spot.
I can live with this patch as-is, so weak ACK in case you want to wait
for any other opinions.
I removed such changes as you noted above, where there were more than
one line, and pushed the patch.
