fugitive.vim 3.4

* Use jobs for all Git execution.  Faster and less prone to user error.
* Stream :Git! to the preview window.
* Make :Git grep behave like other :Git commands, not :Ggrep.
* Silence output and open quickfix list on :Ggrep -q.
* Support :Ggrep outside repository with --no-index.
* Expand ##, $ENVVAR, and ~/path in arguments to :Git.
* Expand "%" and other special sequences during tab completion.
* Improve tab completion for :Git push.
* Disable -- More -- prompt on :Git push, fetch, and --no-pager.
* Provide FugitiveObject/FugitiveStageBlob/FugitivePager events.
* Simplify :Gdiffsplit "smart" split direction.
* Support jump to commit in :Git log --graph.
* Use local not upstream branch name for :GBrowse default.
* Better support for ssh config in :GBrowse.
* Replace older deprecation warnings with error messages.
* Assorted public API enhancements.
* Require Git 1.8.5 or newer.
* Require Vim 7.3 or newer.  Full functionality requires Vim 8.1.
* Directly echo :Git output for trivial commands like "add" on Vim 7.
* Fix E1208 when loading plugin on Vim 8.2.3141.
