Comment (by rcurtin):

 One option is just to use the constructor of std::string that allows
 repetition of a single character, i.e.

 std::string ToString(const size_t n)
   std::string indentation(n, ' ');

   // All the other crap

 That takes up the same amount of code as a one-line function call;
 however, there may be benefits of having a standalone function.  If so, my
 suggestion would be that we put it in the Log class, but I'm not really
 sure how much I like that solution (Log::Indent(const size_t), probably
 returning a string, or maybe just Log::Indent(const size_t,
 std::stringstream&) that just puts the spaces into the stringstream).

 So those are a couple ideas, but if you have a better idea, go ahead and
 do it.
