Fixes arduino#206 The sample code from the issue provided a smart way to cheat the dumb FP parser. In fact, the & is referred to the return type (correct) but the comparator doesn't know about semantics and simply prepends the ampersand before searching for the match. So the code matches itself, which makes absolutely no sense. Avoiding this occurrence fixes the issue, however the entire code for prototype line insertion should be refactored in a saner way (see arduino#180 and arduino#191 for another problem)
