            Bug ID: 38069
           Summary: clang-format creates extra space in objective-c array
                    literal if it contains "class"
           Product: clang
           Version: trunk
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal

when formatting

NSArray* simpleClassArray = @[[NSNumber class]];

clang-format adds an extra space

NSArray* simpleClassArray = @ [[NSNumber class]];

the following code is formatted as expected:
NSArray *simpleOneElementNSNumberArray = @[[NSNumber numberWithInteger:1]];
