During the transition to using more async code, I keep running into
https://github.com/rust-lang/futures-rs/issues/2090. Right now, I want
to convert `MergedTree::diff()` into a `Stream`. I don't want to
update all call sites at once, so instead I'm adding a
`MergedTree::diff_stream()` method, which just wraps
`MergedTree::diff()` in a `Stream. However, since the iterator is
synchronous, it needs to block on the async `Backend::read_tree()`
calls. If we then also block on the `Stream` in the CLI, we run into
the panic.
Summary: Codespell actually matches local files at the root of the repo with the
`./` prefix, so without it the `skip` field won't match. Fix this for `./target`
and `./.jj` directories.

We had similar code in two places for restoring paths from one tree to
another. Let's reuse it instead.
I put the new function in the `rewrite` module. I'm not sure if that's
right place. Maybe it belongs in `tree`?
Since gix::Repository::config_snapshot() borrows the repo instance, it has to
be allocated in caller's stack. That's why GitBackend::git_config() is removed.
My gut feeling is that gitoxide aims to be more transparent than libgit2. We'll
need to know more about the underlying Git data model.
Random comments on gix API:
* gix::Repository provides API similar to git2::Repository, but has less
"convenient" functions. For example, we need to use .find_object() +
.try_to/into_<kind>() instead of .find_<kind>().
* gix::Object, Blob, etc. own raw data as bytes. gix::object and gix::objs
types provide high-level views on such data.
* Tree building is pretty low-level compared to git2.
* gix leverages bstr (i.e. bytes) extensively.
It's probably not difficult to migrate git::import/export_refs(). It might
help eliminate the startup overhead of libssl initialization. The gix-based
GitBackend appears to be a bit faster, but that wouldn't practically matter.

Otherwise, the initialized repo could have a different work-dir path than the
load()-ed one. libgit2 appears to do some normalization somewhere, but gix
won't.
I've enabled the "index" component from the "basic" feature set, which would
be needed to implement colocated repo functionality. The doc suggests that
a library shouldn't activate "max-performance-safe", but our crate is also
an application so it would be okay to enable the feature. We'll need "parallel"
anyway to make GitBackend Sync.

If we create a `ColorFormatter`, add some labels to it, print
something using the configured style, and then return early because of
an error, we would leave the terminal in a bad state. I think many
shells reset color codes after a command returns, but let's still do
our best.
Like "jj log PATHS...", unmatched name isn't an error. I don't think
"jj branch list glob:'push-*'" should fail just because there are no in-flight
PR branches.
