FugitiveVimPath() is intended to potentially convert between UNIX and
Windows paths in mixed environments. Let's separate uses that require
that from those that simply normalize slashes.
The `:p` flag resolves symlinks, so the resolve() call is a no-op, and
the subsequent conditional is always false. It also appears to be no
longer necessary, though I'd have to do a bit more digging to figure out
why.
The 2 slash version slots the drive letter into the host field, which
I'm worried will cause problems when the URLs are used non-opaquely, for
example, with an LSP. Let's start transitioning to the convention used
by file:// URLs.
Using $GIT_DIR/index for the summary buffer has 2 problems:
* It requires a BufReadCmd for all files named "index", necessitating
special handling for false positives.
* It forces us to resolve ".git" files and symlinks, decoupling us from
the worktree and thus forcing us to depend on `core.worktree`. Git
always sets this when necessary, but users and third-party tooling
sometimes do not.
Using a fugitive:// URL for the buffer solves both.
This is a large, breaking change, so let's leave $GIT_DIR/index as the
default for now.
The requires dropping support for b:netrw_curdir, which was added in
fecd42864a for the vague reason of
handling "unusually named netrw buffers". I'll figure out what to do
about those alleged buffers when one of them surfaces again.
* Lazy initialization.
* Make status buffer diff retrieval asynchronous.
* Support jump to diff from :Git log --name-status.
* Use smudge filters when viewing blobs.
* Provide User FugitiveEditor event.
* Provide FugitiveRemote() API function.
* 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.
Patch 8.1.560 is the gift that keeps on giving. Let's work around this
for now by bolting on a new behavior to the previously unused :0,0Git
blame. Long term, we probably want to come up with a different
interface.
