Re: [PATCH 15/15] for-each-ref: use get_pretty_userformat in --pretty

> Use get_pretty_userformat() to interpret the --pretty string.  This
> means that leading you can now reference a format specified in a pretty.*
> configuration variable as an argument to 'git for-each-ref --pretty='.

>
> 2. No built-in formats are available.  The ones specified in
>    pretty-formats (oneline, short etc) don't make sense when displaying
>    refs anyway.
