we set for c-backslash-column, so macros with lines longer than 72
would be formatted icorrectly.
Fix brace-list-entry - it doesn't need extra indentation. Pointed out
by roy@. While here use '+ instead of 8 to express "full indentation
step".
XXX: Do we really want brace-list-open indented one step? It might
work for one-liners, but we have lots of longer init lists that are
formatted with brace-list-open of 0.
