nit: Don't need curly braces here; inconsistent w.r.t. the loop on 29

Done.

vector has a begin/end constructor that should work...
std::vector<std::strsing> font_families(sorted_families.begin(),
sorted_families.end());

This is now an 'out' param rather than return value. I'll remember that ctor for
next time.
