[clang-format] SpacesInSquareBrackets should affect lambdas with parameters too
This patch makes the SpacesInSquareBrackets setting also apply to C++ lambdas with parameters.
Looking through the revision history, it appears support for only array brackets was added, and lambda brackets were ignored. Therefore, I am inclined to think it was simply an omission, rather than a deliberate choice.
