            Bug ID: 41899
           Summary: [clang-format] PointerAlignment: Left leads to useless
                    space in lambda intializer expression
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

$ cat .clang-format
Language: Cpp
BasedOnStyle: WebKit
$ cat x.cpp
int main()
{
    auto a = 1;
    auto lambda = [&a = a]() { a = 2; };
}
$ clang-format x.cpp
int main()
{
    auto a = 1;
    auto lambda = [& a = a]() { a = 2; };
}

The space "& a" looks strange when there is no type in the lambda's intializer
expression. This can be worked around with by setting "PointerAlignment:
Right", but ideally "PointerAlignment: Left" would not add a space in this
case.
