Subject: Format unions like structs and classes.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1774603d8b34f86bd254d85a125592fcb323a488;p=clang

Format unions like structs and classes.

Note that I don't know whether we should put {} on a single line in this
case, but it is probably a theoretical issue as in practice such
structs, classes or unions won't be empty.

Before: union A {}
        a;
After:  union A {} a;
