Style bot is complaining about this existing line. I'll revert this whitespace change or fix the style if the reviewer is so inclined.

nit: I'd like to move these function definitions to ReplaceSelectionCommand.cpp in order to reduce the header size.

nit: These function should be "const".

Need a blank line before the private: label.
