Fix Fugitive activation when historical version does not exist

Browse Source 
I believe I omitted BufNewFile here because it seemed like kind of a
silly event for an unmodifiable, unwritable buffer, but I wasn't taking
into account that event is needed for Fugitive to activate.

Closes https://github.com/tpope/vim-fugitive/issues/1261
