We now catch bare {s that should be on the previous line with a do,
while, if, or for, and elses that should share a line with their
preceding }.

That is,
    if (foo)
    {
and
    if (foo) {
      ...
    }
    else

are now detected.

We should think about maybe making Tor uncrustify-clean some day,
but configuring uncrustify is an exercise in bizarreness, and
reformatting huge gobs of Tor is always painful.
