This revision tweaks the internals of the StringToString flag type to ensure that pointers are consistent across invocations of FlagSet.Parse(), Flag.Set(), and FlagSet.GetStringToString(). Prior to this change, each call to GetStringToString would allocate and return a new map. Although this provides nice encapsulation, it means that users cannot manipulate the map (in tests, for instance). To address this, GetStringToString now returns the map directly from Flag.Value. Set() now avoids new allocations as well, updating the existing map over allocating new ones. Documentation for all StringToString flags have been reworked for improved clarity. The tests for this flag type have been completely reworked. A small example demonstrating this flag type was also added.
