[PATCH v4 1/2] repo: factor repo usage strings into shared macros

[Mahi Kassa <mahlet.takassa@gmail.com>]

Factor the "git repo info" and "git repo structure" usage
strings into shared macros so they can be reused in multiple
usage arrays.

This is a preparatory refactoring for subsequent changes to
subcommand-specific help output.
