   1pretty.<name>::
   2        Alias for a --pretty= format string, as specified in
   3        linkgit:git-log[1]. Any aliases defined here can be used just
   4        as the built-in pretty formats could. For example,
   5        running `git config pretty.changelog "format:* %H %s"`
   6        would cause the invocation `git log --pretty=changelog`
   7        to be equivalent to running `git log "--pretty=format:* %H %s"`.
   8        Note that an alias with the same name as a built-in format
   9        will be silently ignored.
