This implements the changes suggested in tpope/fugitive#415.
s:repo_configured_tree is now a global, s:configured_tree() that caches
the bidirectional relation between the worktree and the git_dir.
extract_git_dir() now uses that relation to check whether the
directories it scans are valid worktrees known by the repo at $GIT_DIR.
Taking experimental out of the name, but small tweaks may occur before
then next release.
For future compatibility, any third party handlers should bail and
return an empty string if any of the following are true:
* More than 2 arguments are given.
* The second argument isn't a dictionary.
* The dictionary doesn't contain a "remote" key.

According to `:help E302`, E302 comes from Vim being unable to rename
the swap file when an open buffer's name is changed; but the error is
mostly harmless. E302 seems to occur in vim-fugitive under Windows but
not *nix.
This fix allow :Glog and :Gdiff to work on such systems; previously the
uncaught error made these operations fail or at least work strangely.
On Windows, if Vim is invoked with a working directory starting with a
lowercase drive letter (e.g. c:\<path> instead of C:\<path>), some
mappings in the blame buffer do not work correctly. For example,
hitting Enter on a line throws an exception rather than showing the
associated commit. The reason for this is that the b:git_dir variable
is not being set on the blame buffer. The reason in turn for this is
that the path to the blame buffer is being stored in s:temp_files with
an uppercase drive letter, but in the fugitive_temp augroup, '<afile>:p'
is being expanded with a lowercase drive letter, so the lookup in
s:temp_files fails. Fix this by converting paths to lowercase before
using them as keys for the s:tempfile dictionary. Because of the way
Vim generates temporary file names, this is safe even on platforms with
case-sensitive file systems.
Our doautocmd in s:ReplaceCmd already processes the modelines while the
buffer is still modifiable, so we can disable it after tha prevent
subsequent invocations.
Closes#323.
This reverts commit d6540b2588, which
caused all sorts of breakages with buffer names with brackets in them.
This was greatly exacerbated by airline.vim setting an erroneous
b:git_dir in plugin buffers based on the current working directory.
Closes#464. Closes#463. Closes#461.
There are rare situations where a user has manually specified what they
wish to use as their work-tree directory, and even rarer situations
where the user wishes the Git directory to be customized. In the case
the user has set these using environment variables, vim-fugitive takes
advantage of these settings in order to set up.
Note that git-config(1) allows setting the work-tree and Git dir in
a number of ways (see the core.worktree) setting. This change only
respects the environment variable method, not the config file method.
The algorithm in fugitive#extract_git_dir() is to move upwards in the
file system hierarchy until a sub-directory called .git is found. When
accessing a file on a network share from a Cygwin Vim and the file is not
within a git repo, this eventually causes a check for the existence of
//serverName/.git and //.git. Such checks are extremely slow so let's
avoid them.
This reverts commit 31dead6d80.
Generating the tags file after already loading the buffer burns me over
and over and over again, and I'm not convinced there was a problem to
begin with.
When using a :Gedit command from the :Gstatus window the git_dir was
being based on the window that was switched into in order to edit the
file. So if Fugitive switched into a window with a file from a different
Git repo (or a file with no Git repo) the :Gedit command could fail or
edit the wrong file.
Instead base the git_dir on the window from which the :Gedit command
originated.
