Comment out small block of code that doesn't do anything

There's a small block of code that calls strnlen on a string, saves
the esult in a variable, conditionally decrements the variable, and
then does nothing with it, making the entire block of code a no-op.

I don't want to just remove it entirely since it's possible that there
was intended to be some sort of check here that was inadvertently
omitted. So to make the compiler stop complaining I've commented out
the code, but I've left a comment above it explaining why it was
commented out and pointing out that maybe something different needs to
be done with it.
