Why does the History command not specify --tiebreak=index?

This is a question, and depending on the answer, a feature request. For the `:History` commands it is very useful to be able to quickly get the recently used entries. For that reason `:History:` and `:History/` specify only `--tiebreak=index`, because getting the most recent entry almost always trumps the shortest command.

I would argue that the same logic would apply to `:History` (file history), but it doesn't specify `--tiebreak=index`. It uses the default `length, index` tiebreak, which means that file you opened 10 mins ago gets less preference than the file you opened a week ago which has a slightly smaller path.

So my question is, why doesn't `:History` specify `--tiebreak=index`? I really would argue that 'get the most recent matching file' is almost always what the user wants.
