again- could probably wrap Follow with FollowWithFields

if err != nil || len(s) == 0 {
break fields
}
s = s[:len(s)]

Thanks for reviewing.

The EnumerateData call allows us to walk over all the different fields in the journal file. Now that I think about it, this can likely be done with multiple calls to GetData as well. Which would likely make it more efficient

Actually in retrospect, i think this method should be called FollowWithAllFields because many people end up using custom fields in their journal entries. This allows the user to have the option to filter or not.

I think the best way of doing so would be taking out the fields map[string]struct{} parameter to the function
