Doxygen comment generation can overwrite the function signature if it's invoked to the left of the signature

[sean-mcmanus]

Reported on VS at https://developercommunity.visualstudio.com/t/Auto-generated-Doxygen-comments-are-wron/10943572 but their implementation is different.

Start with

/**/ inline int func(int i) {
  return 0;
}

and typing * between ** gives:

Or just type /** when there's whitespace to the right of the cursor and before the function signature.
