Subject: [PATCH] Don't rely on current buffer's Git dir for :GBrowse

This makes :GBrowse fugitive://... work when the buffer name is from a
different repository.  It doesn't solve the harder problems of making it
work with a regular filename, or making it not bail early when the
current buffer doesn't belong to a repository at all.
