Comment (by teor):

 There's another way of implementing this patch, that will print all
 current and future fallback directory fields:

 The current fallback directory code `#includes` the list of fallbacks in a
 static array that's inside a function.

 If we refactor that code, creating a default_fallbacks static variable at
 file-scope, then we can simply print out the content of each fallback
 string.

 But your existing code may still be useful - it can be used to print out
 the fields from fallback directories that are configured in the torrc. (We
 can imitate what happens for authorities.)

 What do you think?
