Most likely. I imagine I tested around a bit until I got it to work. :) 

As you have noted, keeping track of what the proper level of m4 quoting should be is quite mind-killing, so we have basically not done that, but just tried adding or removing quoting until stuff starts working, if it breaks. Most places m4 is quite tolerant against both too much or too little quoting.
