No, this is way better than the existing code. I introduced it to get
away from strcpy(), but this is better still. But...

Yes, this seems even better. If our goal is just to start our new
grep_opt the same as grep_defaults, then a single-line struct copy
(whether through assignment or memcpy) is even clearer and more
maintainable.
