The archive command does three things during its
initialization phase:
1. parse command-line options
2. setup the git directory
3. read config
During phase (1), if we see any options that do not require
a git directory (like "--list"), we handle them immediately
and exit, making it safe to abort step (2) if we are not in
a git directory.
Step (3) must come after step (2), since the git directory
may influence configuration. However, this leaves no
possibility of configuration from step (3) impacting the
command-line options in step (1) (which is useful, for
example, for supporting user-configurable output formats).
Instead, let's reorder this to:
1. setup the git directory, if it exists
2. read config
3. parse command-line options
4. if we are not in a git repository, die
This should have the same external behavior, but puts
configuration before command-line parsing.
