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.

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.
This avoids https://github.com/rust-lang/futures-rs/issues/2090. I
don't think we need to worry about reading legacy conflicts
asynchronously - async is really only useful for Google's backend
right now, and we don't use the legacy format at Google. In
particular, I don't want `MergedTree::value()` to have to be async.
Both local and remote refs are backed by the same value type since we'll need
some kind of runtime abstraction to represent "branches" keyword (which is a
list of local + remote branches.) It's tedious to implement separate
local/remote/both ref types.
The "unsynced" flag is inverted just because the positive term is slightly
easier to document.
I'm going to change "branches" to return a list instead of formatted string,
and I don't think "if(branches, ..)" should be invalidated by that. Perhaps,
a container type like String, Vec<T>, Option<T> can implement the cast.
Makes sure that, at the point the commit summary for the new commit is written,
the original commit that is being rewritten is already abandoned. Otherwise,
once we show divergent change ids (in a subsequent commit) in the short commit
template, the commits would be shown as divergent.
This also has an effect on whether branches are displayed next to the commit;
the changes in test_resotre_command happen because, now, the branch is properly
propagated to the restored commit before its summary is displayed.
test_templater_alias(), test_templater_alias_override(), and
test_templater_bad_alias_decl() aren't moved since they also test config loading
and error formatting. The first test in test_templater_parse_error() is left for
the same reason. test_templater_upper_lower() depends on the commit templater.
