I cannot reproduce this in VA 2036 and VS2010, but I can reproduce it in VS2013. Since this is VS2013 specific for me, I don't think that this has anything to do with VA, at least not for me. VS2013 has added C++ formatting rules, and these rules are applied when code is edited or inserted, and the IDE will update the formatting of code VA touches. If this is what is happening to you, then you need to set the IDE C++ code formatting rules so they match the code formatting you are using.
Have a look at all of the settings under:
IDE tools menu -> Options -> Text Editor -> C/C++ -> Formatting
