René ScharfeAs suggested by Junio, --pretty=format can be sped up by avoiding to call find_unique_abbrev() if it's not needed. This is quite easy after the "pretty describe" series, as interp_count() exists and has already been called to avoid the (even bigger) overhead of the describe placeholders.
